Contents The Inside Story This is a catalogue for potters, sculptors, tilemakers and ceramists in craft, education and industry. Generally we have sought in its pages to bring together a combination of our own manufactured products with a selection of other brand names, many from prestigious international suppliers for whom we are U.K. distributors. In addition we have sought to provide much useful technical data so as to enable not only easier selection of the product most suitable for a particular requirement but also to provide important health and safety information. We endeavour to cater for all degrees of skill: for the expert we offer a wide range of clays, glazes, colours etc., suitable for use in advanced techniques and capable of giving superb results. On the other hand, we appreciate the difficulties of the less skilled and hence provide literature and technical advice to assist in the choice of materials, equipment and making methods.

Botz, Mayco, Spectrum glazes. Plastic Ware, Plaster Moulds, Clothing We have been renowned as leading suppliers of clay for over seventy years, most of these clays being based upon the unique deposits taken from our clay mines at Brownhills, South Staffordshire. In the last twenty years or so we have substantially increased our manufacturing capabilities to include the manufacture of specialised grogs, a comprehensive range of glazes and a wide range of top quality kilns of both electric and gas fired types. Whilst our product range is now very extensive we would however emphasise that our marketing strategy is based upon flexibility and we are able to produce clays, glazes and kilns to customers specification. If you therefore require a product not included in this catalogue, or you require any amendment or modification, do please let us know.

Front cover illustration from a woodcut by Picolpasso 1 SECTION 1 Clay Selection Selecting Clays All our clay bodies are in ‘plastic’ form, packed in 12.5 or 25kg packs, and ready for use. When stored in a cool but frost free situation, free from draughts and direct sunlight, the clay packs will retain their condition almost indefinitely. For general use we particularly recommend 150-1102 and 151-1124 bodies, both of which are slightly grogged. If a smooth clay is preferred then we suggest clays 159-1131, 1591135, or 159-1137 (red), 151-1120 (buff) or 158-1141 and 158-4130 (white). For more specialised needs the chart and data given on pages 3-4, 6-7 and 68 will assist. The grogged clays, incidentally, may not permit such finely detailed or turned work but they have increased resistance to warping and cracking. Clays of wide firing range: Some clays have very wide firing ranges, enabling them to be used for earthenware (1100-1150°C), middle temp. (1180-1220°C) or stoneware (12201300°C). These are: Buff firing: 150-1102, 151-1120, 151-1124, 157-1150 Red firing: 159-1131, 159-3140, 159-1134 White firing: 158-1141, 158-2144, 158-4130 Technical Data See page 68 for typical analyses etc. Glaze Suitability/ Firing Temperatures We recommend biscuit firing at 10001060°C then following with a glaze firing to a higher temperature which matures both the clay and the glaze at the same 2 time. Each clay body and each glaze is catalogued with its firing range. When selecting a glaze for use with a particular clay it is important to select one with a firing range which exceeds the lower figure given for the clay. If this is not done the clay will be underfired and the glaze consequently may craze. Alternatively one could biscuit fire the clay above the lower figure given for the clay then glaze fire to the firing range of the selected glaze. However, this method may cause difficulty with glaze pick-up when dipping (although this can be overcome: see 3442 page 22). Bone china is invariably produced this way. Firing Rate The optimum rate depends upon the thickness of the pots and clay type e.g. thin cast and grogged bodies can be fired quicker than thrown and ungrogged ones. Ideally, biscuit firings would be slower than 100°C per hour up to 200°C and 100 - 200°C per hour beyond that point and ending with a short soak. Glaze firings should be at 100-130°C per hour but at 100°C per hour maximum from 700-1100°C with high carbon ball clay or fireclay based bodies. Maximum Firing Temperature This is approximately indicated by the vitrification point stated for each clay on page 68 but, with stoneware, it will be lowered by reduction firing conditions and is dependent upon other factors such as firing cycle. Consequently this figure is given only as a guide for comparison purposes. If clays are fired above their vitrification point then bloating is likely. Bloating may also result from insufficient biscuit firing or too fast firing in the later stages of the glost firing. Conversely, overlong firings may give excess heat work and cause bloating. Recipe Amendments Recipes of heavily grogged panmilled bodies 153-1114, 153-1153 and 1541154 were amended from May 1998 to give improved resistance to lime popping and efflorescence problems. These changes involve using new refractories instead of reclaimed firebrick as the grog source, finer processing of certain other clay constituents and a recipe change with 153-1114 - which is now listed as 153-3114 Premium Craft Crank. The fired colour may be slightly different under certain firing conditions and a fired trial is therefore recommended. Other properties, including their superb handbuilding performance, remain the same. Manufacturing Code: * Bodies marked P are finished by our Panmilling technique. This gives excellent, reliable control of grog and water contents but is more open to occasional contamination from larger or extraneous particles arising in the ingredients or during processing. It generally produces better moisture control in grogged bodies. S denotes sliphoused bodies. These are prepared in very large batches in slip form which is finely sieved prior to or after grog addition. The purified slip is then pumped into presses for dewatering prior to pugging. Sliphousing gives greater product uniformity and virtually guarantees freedom from contamination. Its disadvantage is that it is more difficult to control grog contents (due to settling from suspension) and moisture content. It is the best technique for smooth textured bodies. Plastic Blended Clays PB denotes Plastic Blended bodies. Our latest development here at Potclays is the introduction of our plastic blended range of clays. Using this process, we are able to combine the benefits of sliphousing, for maximum purity, and lowlime wet processing, for accurate control over grog and water additions. These clays offer an alternative to their powder blended equivalents at a more competitive price.

Both tolerant and resilient it has good warp and crack resistance and is suitable for throwing and slabbing. New Keuper Red 159-1131 This high quality, smooth earthenware body has a low flux content to improve glaze pick-up and enabling it to be used at higher temperatures. When fired above 1200oC the body takes on a purple tone. Reduction St Thomas 150-1104 An attractive toasted stoneware in oxidising conditions this body really comes into its own under reduction. The excellent handling properties make it a popular choice for domestic stoneware production. White St Thomas 150-1106, 150-1506 A light grey-white colour in both oxidation and reduction combined with outstanding handling and resilience make this body the first choice for small and large work alike. The 150-1506 version is particularly free of natural speckles, and both will withstand high temperatures. General Stoneware Buff Stoneware 151-1117 An inexpensive fireclay based body which throws well, turns easily, and is plastic, strong and reliable making it highly suitable for domestic ware. Buff School Clay 151-1120 Popular with stoneware potters as a production body for both oxidation and reduction, this dual purpose earthenware and stoneware clay is equally suited to use in schools. The fireclay, ball clay and china clay blend produces a body of smooth texture and medium shrinkage. Sanded Buff 151-1124 A lightly sanded version of our Buff School Clay, this body has a much greater tolerance to making methods and is an excellent choice for school use. New Lavafleck 151-1514 This new version of our highly flecked stoneware body is popular for its distinctive character. Having good throwing ability, it is now more temperature stable. Shelves need to be well coated with refractory wash to prevent sticking during firing. 6 Keuper Sanded Red 159-3140 Superb body for tiles, slab work, large pieces and murals alike, this body has high resilience and good warp resistance, yet the smooth texture allows detail to be captured. Grogged Red 159-1134 When used at either earthenware or stoneware, this body has good general properties, low shrinkage, and is excellent for large pots. Firing to a terracotta colour at earthenware the colour gradually changes with increasing temperature to a warm toasted brown. Original Red S/E 159-1135 Carefully graded and blended red clays and fireclays give this, our original, terracotta body outstanding tolerance and physical properties. It is a good domestic earthenware body which throws and turns well. Red Earthenware Terracotta 159-1137 This competitively priced body is a high quality blend of red clays and fireclay which give it a good colour and high fired strength. Sanded Red 159-3730 Based on our 159-1137 body, a small addition of sand enables this body to be used for larger forms and increases warp resistance making it suitable for tile production without detracting from the pleasant terracotta colour. Chocolate Black 159-2130 Especially good for sculpture this competitively priced clay fires to a chocolate black colour at earthenware temperatures and has a fine texture. Smooth Throwing Stoneware Flecked Stoneware 152-1109, 152-2109 Based on a blend of ball clays, this attractively flecked body is excellent for thrown domestic ware, large or small pieces. The carefully graded fleck burns through covering glazes giving a reduction fired appearance in an oxidised firing. The 152-2109 version is similar to 152-1109 but is based on higher purity sliphoused materials and is more attractively priced. Stoneware Body 152-2110 This highly plastic throwing body designed for use in oxidised and reducing conditions, is suited to thrown domestic ware particularly where colour response is important. Crank Clays Ivanhoe 152-1112 This traditional formulation is superb for tiles, slab work and murals due to its excellent warp resistance and resilience. Although it has a high grog content, the smooth surface texture allows detail to be captured well in the toasted colour. Craft Crank 153-1114, 153-2114 Regarded by many as the best crank clay available, Craft Crank is unsurpassed as a handbuilding clay. The unique blend of fireclays and ball clays produce a pleasant toasted colour in oxidation whilst the speckled orange-brown under reduction is unrivalled. The 153-2114 version is similar to 153-1114 but is based on higher purity sliphoused materials and is more attractively priced. Premium Craft Crank 153-3114 This body offers the same properties as our original Craft Crank, but with an all ball clay base. This gives the body a smoother clay base whilst retaining the same fired colour. Sculpture Crank 153-7070 A variation of our Craft Crank specially formulated for larger sculptural work. It contains slightly more coarse grog grades than Craft Crank and has a more open texture. Grogged Pink 153-1127 Obtained by a carefully controlled blend of Crank and red clays, it is a general purpose handbuilding body, which fires to a pleasant pink colour at lower temperatures and gradually darkens as the temperature increases. Industrial Crank 153-1153 Suitable for large sculptural work, slabbing, saggars and raku, this body is very refractory having an open texture with low shrinkage and good warp resistance. Raku Raku 154-1154 With superb thermal shock resistance and low shrinkage this body is not only excellent for raku work, but is also highly suited to slabbed work and is capable of firing to stoneware. Coarse Raku 154-1156 With coarser grogs present, this body is designed for those producing large sculptural forms which are intended for either raku or stoneware firing. The coarse textured grogs produce a pronounced fleck when fired to stoneware. Smooth Raku 154-1159 Specifically designed for those who want the strength and resistance for raku firing but in a body which can be thrown, slabbed and coiled, it contains more medium range grogs. Tandoori (only available by the tonne) 154-0131 Intended for industrial applications, this body is specially designed for the production of Tandoori ovens where high strength and excellent thermal shock resistance is required. This very coarse body is not recommended for general use or for sculptural items where a high selling price is anticipated. White Grogged Stoneware White Crank 156-0630 White firing, this body is based on a blend of ball clay and china clay to which is added graded molochite grogs. It is excellent for the production of large forms, slabs and tiles, and can be fired to stoneware as well as used for raku. T Material 156-1161 Extremely resilient and tolerant, this off-white firing body is superb for large sculpture and handbuilding use. Its low thermal expansion, low shrinkage and good warp resistance mean that it is well suited to high quality raku pieces. Y Material 156-2161 White firing, this blend of ball clays and china clay with molochite grogs is the ideal choice for high quality raku pieces. Its low shrinkage and excellent warp resistance combine well to produce an outstanding sculptural body. Porcelain Casting Porcelain 155-1550 Porcelain on a budget could be how this body is best described. The off-white fired colour and semi-translucent finish enhance the temperature and shape stability of this body, making it ideally suited to pieces where porcelain is required but high whiteness and translucency is not of primary concern. DL Porcelain 155-1147 Similar to the original David Leach body, this white, translucent porcelain is excellent for throwing. HF Porcelain 155-1149 This truly excellent white-burning translucent porcelain developed by Harry Fraser combines the finest quality and value. It throws well and is consistent and reliable. JB Porcelain 155-4000 Whiter firing than almost all other porcelains, this body offers good throwing properties combined with high translucency and quality at an affordable price. Southern Ice Porcelain (LBSI) 155-1151 Developed in Australia by Les Blakebrough, this truly outstanding porcelain is the whitest firing and most translucent porcelain available. The unique blend of high plasticity Australasian china clays set this body in a class of its own. Cool Ice Porcelain 155-1152 Developed in Australia, an outstanding low temperature translucent porcelain. The unique blend of high plasticity Australasian china clays set this body in a class of its own. Bone China 155-1148 This traditional Stoke on Trent Bone China body offers users the whitest firing clay available. Like all bone china, it is best suited to slip casting or machine making, but with suitable plasticiser additions it can be converted to a ‘flower making’ clay. White Stoneware White Stoneware 157-1145, 157-2145 This superb white stoneware body, based on carefully selected china clays and ball clays, has just sufficient added flux to maintain temperature stability yet provide exceptional ‘ring’. Excellent for small and large thrown domestic ware it stand up well even when thrown thinly. New Draycott White Stoneware 157-1143 A white firing blend of ball clay, china clay and fireclay, to which a small addition of molochite grog is made, produce a smooth body suitable for throwing and modelling both small and large domestic items for oxidised or reduction firings. Modelling Clay 157-1150 Used by model makers for all types of projects, from original china figure models to film special effects, this clay is the most plastic modelling clay available. White Earthenware Ivory Earthenware 158-2138 A good earthenware body for slip casting of general and domestic ware. Studio White Earthenware 158-1141 This ball clay based, very plastic white firing earthenware is well suited to thrown ware. It has a good green strength and wide firing range. Grogged White 158-4130 Based on the 158-1141 to which we add a small addition of graded white grog, this body has exceptional handling properties for larger items and yet can still be easily thrown. Grogged White (Molochite) 158-4120 Graded molochite grogs are included in the 158-1141 base clay to give a body which has excellent workability for handbuilding, sculpture and tiles, yet still possesses a high plasticity for throwing. Semi Porcelain 158-2144 A white earthenware, semi-porcelain or Parian body made to a traditional recipe which is generally suited to slip casting or machine making. Smooth in texture but of medium plasticity. The 157-2145 version is similar to 157-1145 but is based on higher purity sliphoused materials and is more attractively priced. Paper Clay White Special Stoneware 157-1142, 157-4230 White firing and smooth textured, this clay throws and handles well and is a very good body for domestic ware. Paper Clay 180-1190 Developed in conjunction with paper clay users, this body is based on a white stoneware to which carefully controlled grades of inorganic fibres and binders have been added, giving all the benefits of Paper Clay without the shelf-life problems. The 157-4230 version contains a small amount of white sand which provides extra shape stability for larger domestic ware and improves the thermal shock resistance. Southern Ice Paper Clay 180-1192 All the wonderful qualities of LBSI combined with the versatility of paper clay. 7 SECTION 1 Prepared Clay Bodies SECTION 1 Powdered Clays & Firebrick Grogs Powdered Clay Bodies 1000-02 Low temperature white e-ware Fires white to off-white from 1020 - 1180.

Porcelain Bone China 9 SECTION 1 Casting & Decorating Slips Frits & Glazes Glazes SECTION 2 This comprehensive range of basic glazes provides the potter with proven, reliable glazes formulated by experienced ceramists and checked by qualified teachers and studio potters. All powdered glazes featured in these pages are classified as either low solubility or leadless. The low solubility glazes contain lead but this is present in a fritted, ‘non-toxic’ form. Such glazes can be safely used in schools and studio potteries since they meet the requirements not only of the Education Memorandum 517 but also the stringent requirements of the Factory Acts. The leadless glazes, of course, do not contain lead as a recipe ingredient and may therefore be considered ‘extra safe’. Glazes marked * apply a thin coat only. L denotes leadless glaze. LS denotes low solubility glaze. 2249M 2250 2251 2320-5 2320-8 2361 2370 2376 2380 Matt white zircon Glossy tin Glossy tin Satin white Opalescent white Glossy white opaque stoneware Frosted off-white matt tin glaze Vellum off-white dolomite glaze Shiny tin glaze L L L L L L L L L 1030-1120oC 1040-1125oC 1100-1160oC 1180-1230oC 1180-1220oC 1230-1300oC 1230-1300oC 1250-1290oC 1240-1290oC L L 1060-1140oC 1180-1280oC 2201 White Crackle.

The opaque or speckled glazes will give particularly good effects when double-dipped to give varying glaze thickness and colour tone. For a huge range of coloured earthenware glazes in brush-on form please see our Mayco and Spectrum sections Glazes on the following list contain a natural flecking material which can be coarse in nature. It is therefore recommended that these glazes are not sieved through a mesh finer than 40’s during preparation. Using a finer sieve will remove some of the natural fleck material thus changing the fired appearance of the glaze: 2246LSM Vellum White 1020-1110oC L. 2247M Chinese White 1020-1110oC L. 2300 Rich Amber 1040-1110oC L.S 2301M Speckled Olive 1040-1110oC L. 2302 Crimson 1050-1110oC L. 2304 Victorian Burgundy 1020-1110oC L.S 2305 Tortoiseshell 1030-1110oC L.S 2306M Yellow 960-1050oC L.S 2307M Honey 1020-1110oC L. 2308 Trans.

Leave to settle overnight and pour off surplus water. Stir, then add water if necessary to achieve desired consistency which depends upon porosity of biscuit ware but normally will be around 18 - 25 ozs. of dry glaze per pint of water (800 - 1250gms per litre) i.e. about 1kg per 1.4 - 1.9 litres water. Glaze Suspension Settling is not normally a problem with Stoneware glazes but may be troublesome with some earthenware or Artistic glazes, the glaze settling into a hard deposit at the bottom of the containers which is difficult to reconstitute. The addition of 1% of Bentonite (3411) to the glaze powder prior to preparation will help prevent glazes from quickly settling and such addition is therefore common practice. Even so, this may have little effect on any tendency for the glaze to set hard once it has settled. A flocculant such as 3415 Calcium Chloride or 3442 Magnesium Sulphate added to the glaze will, however, have the effect of causing the glaze to settle in a more loosely packed arrangement of the constituent parts which are then more easily reconstituted. The method is to mix a little of the flocculant with hot water in a cup until no more can be dissolved. Leave to cool and then add a few drops only of the liquid per litre of glaze, followed by thorough mixing. Larger additions will cause the glaze to thicken (this being helpful if very vitreous pieces are to be dipped). Consistency Measurement Once the correct glaze consistency has been achieved it should be measured so that it can be repeated next time. Weigh exactly 100cc’s of the mixed glaze and dividing the resultant weight in grams by 100 to obtain the specific gravity. Alternatively one pint can be weighed to determine the ‘pint weight’. A popular method is to use our glaze hydrometer (ref 5828 page 38) to quickly obtain a reading which can easily be checked at each glazing session & the glaze adjusted if necessary. Artistic Glazes These unusual and interesting glazes will give the results described when applied thickly and fired on flat surfaces. Vertical surfaces and thinner deposits may give different effects. Glazes marked †should not be used on tableware (see page 64). The remaining glazes are suitable for all wares.

They are completely ‘non-toxic’ and are especially suited for use in education and training establishments wherever safety issues are especially important. However, their distinctive and attractive fired results have made them very popular with potters and hobbyists both as a decorative medium and covering glaze. They can be used conventionally and fired in the range 1200 - 1260°C with a 15 - 30 minute soak or alternatively can be used as a decoration applied under or over other stoneware glazes. They then act as reactive glazes to provide interesting and sometimes stunning combination effects.

Moisten greenware, apply Mender, press firmly together and hold for a few seconds and then remove any excess. Also used to fill cracks in biscuit ware: soak cotton fibre in Mender, fill in the crack and refire. 23 Oxides & Prepared Colours Oxides SECTION 4 The raw pigments from which prepared colours and stains are compounded, oxides may be painted directly onto clay, biscuit or unfired glazed ware (majolica), or used as stains for bodies and glazes producing the characteristic colours described. Further technical data appropriate to this section is given at the back of this catalogue. 4502 Chromium Oxide Versatile pigment producing characteristic opaque green but producing red, khaki or yellow in presence of zinc. Incorporation with tin produces pink (chrome-tin pink). 4503 Cobalt Carbonate 4504 Cobalt Oxide (Black) The most powerful ceramic pigments giving a range of transparent blues ranging from intense blue or blueblack in lead and lead less glazes to a vivid blue in alkaline ones. The carbonate form is weaker but gives less risk of specking. 4505 Copper Carbonate (Cupric Carbonate) 4506 Copper Oxide (Black) (Cupric Oxide) Transparent green under normal neutral or oxidising firing conditions except in alkaline glazes where turquoise is developed deepening to transparent Persian blue in strongly alkaline ones. Under reduction conditions a copper red colour is obtained (sometimes referred to as 24 ox-blood or sang de-boeuf). Carbonate form is weaker but gives less risk of specking. NOTE Copper compounds must not be incorporated into any low solubility glaze if the resultant glaze is to be used on domestic wares in contact with foods. There is no problem with copper in leadless glazes. Ilmenite See page 21. Iron Compounds Iron compounds have great natural variety and are the most popular colouring pigments. In addition to the characteristics detailed below, most of them produce yellow-tan tints (depending on quality and thickness) in lead-tin glazes. At stoneware temperatures black-brown tenmoku effects are developed whilst black and grey-greens are achieved under reduction firing conditions. 4507 Iron Chromate Ferric Chromate Produces grey. Black in combination with cobalt. 4508 Iron Oxide-black Ferrous Oxide 4510 Iron Oxide-red Haematite. Ferric Oxide. 4511 Iron Oxide-red synthetic Ferric Oxide 4512 Iron Oxide - yellow ochre Ferric Oxide. Produces browns and honey yellows in glazes depending upon amount. Yellow ochre weakest but most miscible of the iron oxides. All are good painting pigments. 4518 Vanadium Pentoxide Generally used in combination with tin oxide in glazes to give opaque yellow but also directly as pigment. 4514 Manganese Carbonate Generally produces colours obtained from manganese dioxide but is weaker and more finely divided. Use of underglaze colours. 4515 Manganese Dioxide Black, finely ground powder giving sepia or grey-brown colour in lead and leadless glazes with plum or purple colour in alkaline tin ones. With cobalt, or cobalt and iron, produces good black. Also called manganese oxide. 4517 Nickel Oxide Will produce brownish greens, brown and grey glazes but more commonly to modify or grey the colours obtained from other colouring oxides by combination. 3454 Rutile Ores containing titanium dioxide with iron oxide used to produce a mottled brown colour in glazes - especially in combination with a trace of ilmenite Excellent for modifying other stains or oxides. Buff-brown fired colour. 3467 Tin Oxide (Stannic Oxide). Generally used as a white opacifier in glazes but also useful as a white decorative pigment - either alone or mixed with a little transparent glaze. All colours and stains can be fired up to 1300°C except those marked EW which are stable up to 1140°C but change colour tone above this. All colours in powder form. Underglaze colours may be applied onto clay ware (green hard), or onto biscuit ware using our 3446 media. Mixing of colour and media must be very thorough and is best achieved by working the colour into the media using a palette knife in a rubbing or lapping action. If sufficient flux is added, colours and stains can be made self-glazing and matt colours developed. Powder colours mixed with 3446 Media provide the cheapest and most usual way of applying underglaze decoration. Use of glaze & body stains. Glaze or body stains are normally used for the preparation of coloured glazes (5 8% addition) or coloured slips (10 - 18% addition) followed by sieving through 120’s mesh. They can also be used in maiolica fashion (with flux addition) and generally as underglaze colours in which case a small flux addition (e.g. 2263) is also desirable. All the above colours and stains are manufactured to a stringent safety specification. Nevertheless, care should be taken to avoid them being taken in to the body by mouth or inhalation. When not in use ensure bottles and containers are tightly closed.

Certified AP Non-Toxic and conforms to ASTM D-4236 See Page 17 for more information Brush-on Underglazes Spectrum Underglazes Lead Free, Non Toxic, Fires to Cone 06-6 (1000-1240OC) Ready to use liquid decorating colours that have a very wide firing range from 1000°C to 1260°C. They are extra-safe in that they do not contain any lead, cadmium, barium or zinc in their composition and they are therefore especially suitable for use in schools where they can be considered ‘non-toxic’. The colours are very strong to give rich vibrant colour tones but they can be thinned if necessary with water to enable delicate colour washes etc. Brushes can simply be washed out with water. Furthermore, the colours can be intermixed to produce intermediate tones. A major attraction is that although they are designed as fluxed underglaze colours for application to bisque or clay ware, they can also be used in majolica tradition onto unfired glazed ware or as an overglaze colour onto fired glazed ware. They can be used on earthenware, redware, stoneware or porcelain and are therefore supremely versatile colouring pigments. The fluxed nature of the colours results in them firing matt to semi-matt around 1000°C becoming slightly shinier as firing temperature increases. Available in 30ml jars. A full palette of rich, vibrant colours that are opaque with 3 coats, semi-opaque with 2 coats and semitransparent with 1 coat. They are compatible for use under most clear glazes. Can be applied on greenware or bisque and can be used with or without a clear glaze covering. Chart shows the unglazed colour in the upper left half of the tile and the colour when covered by a clear gloss glaze in the lower right half of the tile. These samples were fired at cone 05. Spectrum underglazes generally have good temperature stability up to cone 6 and for many colours to cone 10. Please note that when fired higher than cone 04 you may get small colour variations from those shown on the chart. 501 1 White 510 1 Tan 519 1 Chamois 4001 Egg Yellow 4002 Cobalt Blue 4003 Red Wine 4004 Black 4005 Chrome Green 4013 Lilac 4008 Neutral Grey 4014 Plum Blue 4009 White 4015 Fern Green 4010 Wood Brown 4016 Birch Green 4011 Basalt Grey 4017 Sun Yellow 503 1 Light Yellow 504 1 Yellow 505 5 Orange 511 1 512 1 513 1 514 1 Aztec Brown Walnut Brown Choc.

See Page 17 for more information 27 SECTION 4 ‘Unidekor’ colours Brush-on Underglazes Amaco Velvet Underglazes Velvets are vibrant, semi translucent, fluxed colours of remarkable versatility and offer three alternative techniques: SECTION 4 1) When left unglazed and then fired 1000C-1100C, they give semi matt surfaces. With slightly higher firing they assume a slight sheen. Glazing is not essential and thus permanent decoration of finely detailed modelling can be done without having the detail rounded away by subsequent glazing. 2) When used in normal underglaze fashion they can be glazed by dipping or spraying using 2205 or other suitable glazes, or transparent brush-on glaze can be used. The colours then intensify and give glossy results. 3) They can be used in majolica fashion on the unfired glaze, the flux content of the colours giving more predictable results. Velvets offer the advantage of taking the guess work out of colour planning. They fire true to colour as applied from the jar and can be intermixed to create a palette of hundreds of shades. They tolerate a wide firing range and can be used on porcelain and stoneware with the exception of orange and red. Velvets vitrify about cone 4-6. They can be used on clay, biscuit or on the glaze and can be applied by brushing, sponging or spraying. 4V301 Flesh 4V302 Beige 4V303 Terra Cotta 4V304 Straw 4V308 Yellow 4V309 Deep Yellow 4V310 Warm Tan 4V313 Red Brown 4V314 Chocolate Brown 4V315 Peach 4V316 Light Pink 4V317 Medium Pink 4V318 Rose 4V320 Lavender 4V321 Lilac 4V322 Purple 4V323 Salmon 4V325 Baby Blue 4V326 Medium Blue 4V327 Turquoise Blue 4V328 Iceberg 4V332 Teale Blue 4V333 Avocado 4V334 Flaxen 4V336 Royal Blue 4V341 Blue Green 4V343 Chartreuse 4V345 Light Green 4V350 Orange 4V353 Dark Green 4V354 Leaf Green 4V355 Shadow Green 4V356 Pearl Grey 4V360 White 4V361 Jet Black 4V366 Teddy Bear Brown 4V367 Mist Grey 4V368 Antique Ivory 4V369 Fawn 4V370 Velour Black 4V381 Amethyst 4V382 Red 4V383 Light Red 4V384 Real Orange Underglaze Application Methods Brushing - Keep the brush fully loaded at all times. For solid coverage, as in back-grounds, apply 3 or 4 coats of colour, working in opposite directions with each layer of colour. Wait for water sheen to disappear between coats. Sponging - Pour colour onto a glazed tile. Saturate slightly dampened fine sponge with colour and lightly pat onto the greenware or bisque; permitting first coat. to dry thoroughly before applying the next. Solid colour backgrounds can be quickly achieved with this method which eliminates the streaking that often appears when using a brushing method. Airbrushing - Dilute colour with water to the consistency required for a smooth spraying application. For solid colour coverage airbrush 3 to 4 coats; for shading, one coat is generally sufficient. Antiquing - Dilute 2 parts colour with 1 part water, for an antiquing solution. Apply to bisque with as large a brush as practical. Allow to dry. Remove the colour from the raised areas with a moist sponge, rinsing and turning the sponge often to produce clear highlights - exposing the embossed design. 28 Overglaze Colours, Lustres, Media & Accessories The ‘Firebird’ range Preparation of Colours Mix thoroughly by working the colour into the media on a very smooth surface using a palette knife in a ‘rubbing’ action. Pick up the required amount of colour on a brush moistened with turpentine if the medium is fat-oil based. Alternatively a water based medium (such as 3444) may be used. In this event use water to moisten and clean brushes. Firing Overglaze Colours Colours and lustres are normally fired in the range 730 - 800oC. Lower firing temperatures will give matter finishes but this is not recommended on the surfaces of ware in contact with foods. The kiln should be well ventilated (vent plug out) until about 450 -500oC to clear away gases from burning away of media etc. Vent plugs can then be replaced and firing continued to 730 - 780oC. Switch off and leave until cool. 4626 Burgundy 4620 Pink 4621 Salmon 4623 Scarlet 4629 Royal Blue 4630 Kingfisher 4631 Lapis Blue 4632 Light Blue 4634 Chrome Green 4638 Lemon Yellow 4639 Naples Yellow 4640 Buttercup 4641 Old Gold 4649 Transp.

SECTION 7 7080-03 Ducting Supplied by the metre. 7082-01 Wet Back Spraybooth This “water-wash” spraybooth has been designed to meet the ever increasing need to protect our environment. This type of spraybooth works on the principle of a curtain of continuous recycling water running down the rear face of the booth. A glaze spray is aimed towards this curtain, the spray being guided by a powerful extraction fan. The glaze is trapped by the water curtain, whilst the air stream is pulled through the booth and into a washable stainless steel pre-filter and finally into a washable filter bag. The excess glaze is washed into the tank and can at a later date be reclaimed depending on the type and colour of the glaze. There is a ball valve to allow the water to be drained and the contents of the tank removed. Any glaze materials can also be removed and disposed of safely. The booth is mounted on four castor wheels. This version is primarily designed to be used by the studio potter and educational faculties for low volume production, therefore the booth does not need ducting to atmosphere, making it portable around the studio environment.

Where this is not given we will assume it is normal UK single phase voltage (230 volts) with neutral. It is important to check the voltage and available power where the kiln is to be positioned. Ask your electrician or Electricity Board if in doubt. 2) Check that the kiln will pass through all doorways and other restrictions and that the access route is flat and firm. Steps and slopes can be a particular problem. Where site conditions are difficult please consult us. For example 54 we can, at extra charge, build front loaders in 'split cabinet’ form for easy assembly on site. Note that L&L and the larger Silver top loading kilns are of sectional construction to enable them to pass through narrow doorways, up flights of steps etc. Guarantee and Maintenance Limited 3 year warranty on all component parts except elements. Full after-sale service. Maintenance contracts available throughout mainland UK. Delivery Many of our top loading kilns are collected in 'hatchback' cars etc but others - and most front loading kilns - are generally consigned by special vehicle. Delivery is normally by lorry or by special van fitted with a tail lift facility. Help is needed either with offloading or in assisting our driver. With assistance kilns can be moved into final position. Delivery is charged extra dependant on distance, kiln size and site conditions. We can take care of everything but delivery arrangements must be discussed with us and agreed at time of ordering. Installation Kilns smaller than 3.1kW can be plugged into a 3 pin 230 volt power socket. Larger kilns have to be wired into the supply through an isolator or switch fuse unit (e.g. cooker point). Kilns of internal height 68.6mm (27”) and also the SK43 can be connected to either a single phase or a three phase & neutral supply. For large kilns, a 3-phase power supply is generally preferable. Connection to either supply is simple for a competent electrician. If in any doubt, contact us. Etruscan top loading studio electric kilns - Great Value!

Vent plugs in sides and lid. Separate reversible base. Stand with castor wheels. Lid operated safety switch and element power-on lights fitted into switchbox for good diagnostics. Lifting handles fitted. Top quality thermocouple and Kanthal elements fitted. A separate wall mounting control box houses a Firemaster 5 (or alternatives, see page 60) temperature controller; a second wall box houses energy regulators controlling separate zones of the kiln; power-on light, zone energy regulator cycling lights; contactor(s) and accessory circuit fuse(s). Both wall boxes are ready wired to the kiln and only require mounting to a wall. Strongly constructed for long life and low maintenance. The extra ceramic paper and the separate wall mounting control box are major features of Silver kilns. The 5mm paper keeps the kiln cooler and the wall boxes allow all important electrical components to work in a cooler environment to ensures good reliability. They are also more convenient to use and reduce installation costs since the power cable to the kiln is already fitted. An optional zone controller is available for very even heat distribution at all temperatures. This uses a separate thermocouple in each zone. S43 & S65 Silver Kilns KILN DETAILS Kiln. Max.

See page 60 for details of venting systems. 56 See the next page for full details of these Frontloading Kilns EP56 Kiln Potclays Gold & EP Kilns Gold front loading kilns are very durable, reliable and exceptionally efficient production kilns of high performance for school or industrial use. They are constructed from the latest high temperature insulation refractories comprising an ultra-efficient brick hot face and back-up insulation to give a 150mm thick wall of exceptionally low conductivity. This ensures extremely low heat loss, very low external temperatures and amazingly low firing costs. Elements, in highest grade Kanthal for long life and fast, economical performance up to 1300oC, are fitted to both side walls and hearth. The robust angle iron framework featuring an integral stand houses ventilated sheet steel panels which are treated with corrosion resistant paints and very attractively finished in grey and black. One large spy hole is fitted as standard into the door (multiple holes to special order only) and a large vent in the roof. See page 60 for kiln ventilation and protective cages. EP Series EP kilns combine the great durability of the 'Gold' kiln design (and have the same robust angle iron construction and hot face brickwork) but using a 115mm wall thickness. This gives a lower capital cost and a quicker cooling rate: factors which will be appreciated in busy production situations. The kilns have been designed to be a cost effective package and incorporate a thermocouple and choice of Hobbymaster, Firemaster or Zonemaster (see page 60) temperature controller which is factory fitted. EP kilns can be seen to give a very good capacity/price ratio. Spy hole: see above “Gold Series”. The kilns are attractively spray finished in grey. *Furniture sets include a range of props.

A truck contained in the kiln can quickly be removed after firing and the kiln door closed to retain the residual heat. This permits the truck to be unloaded and reloaded with exceptional ease and without being exposed to the heat of the kiln. Alternatively a further truck, preloaded with ware, can quickly be placed into the kiln for firing after the fired truck has been removed and shunted to siding rails. The system is less obtrusive, more economical, more durable and more flexible than alternative systems. The trucks run on rails supplied with the kiln. The kiln is built of strong angle iron and steel panels housing 150mm of finest quality hot face bricks and fibre back-up insulation with harder bricks used on adjacent surfaces of the kiln and the trucks. Elements are located in the side -walls and in the kiln cars. The arched roof is fitted with a manual damper but automatic dampers and other features to meet clients' needs can be incorporated. The kilns are supplied from a minimum of 18ft, (510 litres) up to 100ft3 (2832 litres). The Chameleon glass & hobby kiln is the new plug-in home kiln for glass artists and other fired arts enthusiasts. Suitable for fuse glass, rake glass, china paint, low-fire ceramic bisque and glaze, PMC precious metal, even heat treatment of knives and glass. L&L’s unique hard ceramic element holders make it the first small square lid elemented glass kiln for home use for firings virtually free of dusting. A Bartlett controller gives four easily programmed firing schedules. Complete easy-to-follow visual instructions make this kiln ideal for the beginner yet powerful enough for experienced users.

The standard versions have an energy regulator to control firing speed and an indicator to show temperature. At extra cost the kiln stand is a useful accessory, and a variety of optional computer controllers are available (see page 60). The two most popular sizes are shown on the right and in the table below but larger sizes can be made to special order. 58 Gas Fired Kilns 'Thor' kilns - by Potclay Kilns Ltd. Raku Gas Kilns The Thor firing system utilises burners which fire vertically from the base up both side walls. Heat is therefore projected directly upwards to where it is needed without the use of deflection devices. This is more efficient and aids more even temperature distribution. Thor kilns are solidly built of HT1 & 26 grade brick with high quality back up insulation to give 6" (150mm) thick walls mounted in a very strong angle iron and steel cabinet. They have an arched roof and three spyholes in the door. Adjustable batts over the base flue direct combustion gases into the rear vertical flue which is fitted with a slide damper. All kilns have four naturally aspirating burners each fitted with flame failure devices. Flame viewing-cooling ports are fitted in both side walls. At extra cost, solenoid valves and automatic temperature controllers can be fitted. Operates from Propane gas. Complete with burner, regulator and kiln stand. Max temp these kilns have been tested to is approx 1050°C. 81 - 1709RG Kiln 1.2ft3 17" x 9" firing chamber 81-2409RG Kiln 2.4ft3 24" x 9" firing chamber Extension rings 81-1709RE 17" x 4.5" 81-2409RE 24 " x 4.5" Laser Kilns A range of five front-loading down draft kilns of zinc plated sheet steel construction housing layered refractories with ceramic fibre as the hot face.

Special kiln canopies with triple flued chimneys for cool outer surfaces are available for gas kilns. See following photos:- Examples of ventilation canopies Orton Cones The composition and structure of cones is such that they bend and deform when heated for a period of time. i.e.their performance depends upon heat work and not upon temperature only. They are graded according to the amount of heat they will withstand and are placed upright in holders in the kiln where they can be viewed from the spy hole. Orton cones are designed so that when their bases are placed level they lean at an angle of 80 and will bend in this direction when they have reached ‘temperature’. Since their deformation characteristics mirror the maturing characteristics of the ceramic products being fired , Orton cones are an outstanding method of indicating heat work carried out duringfiring. Temperature Measurement & Control It is usual to use a set of three consecutive cones: one to bend below the optimum firing point, one at the optimum firing point and one above. Single small cones are also used in Kiln Sitter controllers. 8202 self-supporting cones are freestanding and do not need cone stands or clay mountings. They are stocked only in 016, 017, 06, 05, 04, 03, 02 , 01, 6,7,8,9 and 10. Others can be specially ordered. After any firing cones cannot be reused. Whatever temperature indicator or controller is used to control a firing it is strongly recommended that Orton cones additionally be used since they monitor heat work rather than temperature. They reliably monitor the effect of heat on the ware load and also the heat balance in various areas of the kiln. Orton cones are of three types: 8200 Standard Size (2.5”high) 8201 Small Size (1” high) 8202 Self Supporting ORTON CONE No. 018 017 016 015 014 013 012 011 09 08 07 06 05 04 03 02 01 1 2 3 4 5* 6* 7* 8* 9 10 11 Approx. bending temp. oC (Temp. equivalent) Cones can be stood in pats of clay or held in special sockets: Heating rate oC per hour 60oC 100oC 150oC 8203-S Triple socket for 8200 cones 712 736 769 788 807 837 858 873 917 942 973 995 1030 1060 1086 1101 1117 1136 1142 1152 1160 1184 1220 1237 1247 1260 1282 1293 722 748 782 802 822 848 869 883 922 948 979 1002 1038 1065 1093 1110 1127 1147 1152 1160 1181 1194 1230 1246 1259 1270 1293 1303 732 761 794 816 836 859 880 892 928 954 985 1011 1046 1070 1101 1120 1137 1154 1162 1168 1170 1205 1241 1255 1270 1280 1303 1312 inexpensive way of connecting a thermocouple to a measuring instrument or controller.

A dry batt can be supported by hand at its centre or suspended between thumb and finger and tapped with a metal object If it does not ring clearly a crack may be suspected. A dull sound suggests the batt is not dry. Always store batts in a dry place on edge. 3404 Batt Wash Batts will very gradually become glazed from repeated glaze firings and, of course, will absorb glaze coming into direct contact. Eventually the batt surface will begin to scale off and has to be chipped away. To minimise /prevent this the batt can be protected by application of batt wash to the upper side. The coating should be regularly checked and replaced as necessary. It is not recommended to put batt wash on the props or on the kiln bricks. SECTION 8 8205 Kiln Batts (Square or rectangular) Thermal Shock Props and large pieces of ware create hot spots on cooling batts. Allow time to cool. Premature opening or 'cracking' of the kiln door creates uneven cooling and must never be done above 200C.

Generally Potclays products present no special hazard in use provided that good standards of industrial hygiene are practised. Users of Potclays products are also assured that: 1. Incorporation of dangerous materials such as arsenic into any formulation has been scrupulously avoided. 2. Potentially toxic materials such as cadmium and antimony are incorporated in the smallest possible quantities consistent with obtaining reasonable results and that any inclusion of lead is in the form of a lead frit of a type approved by the Factory Inspectorate. 3. We are pleased to advise on any matter of safety. SECTION 10 Handling of Materials Most materials are to some extent harmful when ingested. This applies equally to materials found in the home such as washing powders, boracic ointments, polishes, cosmetics, iodine, soaps etc. as well as those of the pottery and other departments. All materials should consequently be handled with care but in the pottery department certain materials deserve special mention. These are barium carbonate, borax, boric acid, silica (flint & quartz),Chromium oxide, Nickel oxide, on-glaze enamels, lustres (including liquid gold), ceramic glazes generally but particularly those containing cadmium, selenium and lithium; and copper compounds. In addition, especial care must be exercised with red lead, white lead, and antimony oxide but we should point out that we do not include these materials in our catalogue range for we believe that their value to pottery departments does not outweigh the risks arising from careless use. We should perhaps mention here that distinction must be made between low solubility glazes (these contain fritted lead compounds) and the hazardous 'raw' lead compounds such as red lead and white lead. Glazes marked 'L.S.' in our catalogue do have a lead content but this is in fritted form and we absolutely forbid the use of the poisonous raw lead compounds in any of our glaze formulations. In this way we ensure that those glazes which do contain lead are of the safe 'low solubility' type which meet the stringent safety requirements of the pottery industry and which are also suitable for use in schools (see Ed. Mem. 517).The majority of glazes in our catalogue - including all the stoneware ones are leadless, and these may be considered to be 'extra safe'. Such glazes have been marked 'L'. 66 In this catalogue the abbreviation 'L.S.' therefore denotes those glazes which are low solubility lead ones and 'L' denotes leadless. Low solubility glazes are widely used in industry and are quite safe from a handling point of view provided that good standards of hygiene are maintained. Certainly they may be no more hazardous than certain leadless glazes and many, many other materials commonly used in the household and indeed in other crafts in schools. When considering toxicity it is consequently necessary to view the matter carefully with a just sense of proportion. It should also be remembered that the bright colours obtained from oxides or underglaze colours used under or in low solubility glazes frequently are impossible to achieve with leadless substitutes. Earthenware slipware for example would generally give duller colours than those obtained when low solubility glazes are used. Dust Problems Some materials which are not considered toxic when eaten may nevertheless be hazardous in dust form. All clays and glazes contain free silica and such airborne dust may produce silicosis if breathed in over a period of time. Reasonable care should therefore be exercised in the handling of all pottery materials. Inflammable Liquids and Materials Materials containing inflammable liquids such as liquid metals, lustres, media for enamelling and printing, oils and turpentine should be stored in a ventilated cool place where smoking is prohibited. Cloths used to clean any spillage of inflammable liquids must be carefully disposed of due to the risk of spontaneous combustion if carelessly stored. Kiln Vapours and Gases Potentially harmful vapours and gases may be evolved when firing ceramic products. Kilns should therefore be housed in a well ventilated room where kiln gases are exhausted to atmosphere. Low solubility - Definition and Test ‘Low solubility glaze' means a glaze which does not yield to dilute hydrochloric acid more than 5% of its dry weight of a soluble lead compound calculated as lead monoxide when determined in the following manner: A weighed quantity of the material which has been dried at 100°C and thoroughly mixed is to be continuously shaken for one hour, at the common temperature, with 1000 times its weight of an aqueous solution of hydrochloric acid containing 0.25% by weight of hydrogen chloride. This solution is thereafter to be allowed to stand for one hour and then filtered. The lead salt contained in the clear filtrate is then to be precipitated as lead sulphide and weighed as lead sulphate. Glazes other than low solubility or leadless ones are prohibited in the pottery industry. Metal Release Problems Certain fired glaze and colours may release lead and other metallic compounds when in contact with acidic foods and drinks over a period of time There is a hazard to health if the amount released is above a certain level and this has led to adoption of metal release tests in many countries. All Potclays glazes and frits are formulated to meet the requirements of the standard metal release tests with a wide margin of safety except for a very few glazes in the Artistic and Economy glaze ranges which we have clearly marked thus:† Such glazes have been designed for exterior or decorative use only and should not be used to glaze surfaces which may hold food or drinks. Frequently potters desire to make additions to standard glazes to obtain certain effects but it must be remembered that the indiscriminate alteration of a glaze formulation may increase its metal release characteristics beyond acceptable limits. There are generally no problems involved in the adjustment of the leadless glazes in this catalogue by the addition of all normal glaze materials except lead or cadmium. In our opinion the low-solubility glazes in this catalogue may be modified by addition of small amounts of all normal glaze materials except lead, cadmium, copper or zinc. However, it is important to realise that the responsibility for the safety of the finished articles rests with the persons producing them since production techniques and conditions may vary widely. For this reason it is advisable to submit finished pieces of ware to an independent testing laboratory before bulk production is commenced. Note that we offer a metal release testing facility at competitive rates. To summarise we would say that all Potclays transparent and white glazes and all Potclays stoneware glazes pass all known safety regulations. Glazes marked † may not pass metal release tests although they are safe to handle. Such glazes should not be used to glaze surfaces in subsequent contact with foodstuffs and beverages. If in doubt we will gladly advise. Metal Release Test Potters are reminded that it is now a mandatory requirement for domestic wares to pass the following tests known as British Standard (B.S.) 6748 Part I and Part 2. BS6748 Part 1 1972 Flatware Lead = 20 ppm (pans per million) Cadmium = 2 ppm Holloware - Lead = 7ppm Cadmium = 0.7 ppm Storage Vessels or any Holloware over 1100 millilitres capacity - Lead = 2 ppm Cadmium = 0.2 ppm The test involves exposure to 4% acetic acid (vinegar) at room temperature for 24 hours. Holloware is defined as 'Any article in which the ratio of height to diameter is equal to, or exceeds one half. Flatware refers to plates, saucers and dishes. BS6748 Part 2 1972 This refers only to cooking ware, i.e. casseroles, oven-to-tableware etc. and the testing is even more severe, involving exposure to boiling acetic acid (vinegar) for two hours followed by a cooking period of 22 hours. The limits specified are as follows: All shapes Lead - 7 ppm Cadmium . 0.7 ppm COSHH, CLAW & CHIP The Control of Substances Hazardous to Health Regulations 1988 (COSHH) which came into force on Ist October 1989, and the Control of Lead at Work Regulations 1980 (CLAW), largely replace the Pottery Health and Welfare Special Regulations 1950. They apply to all premises (including educational establishments as well as factories) where pottery is made or decorated and to the preparation and use of clays, glazes colours, materials etc. The Regulations are concerned with assessment of hazards in the ceramic workplace and demand precautions which are related to the degree of risk involved. The Chemicals Hazard Information & Packaging Regulations 1993 (CHIP) introduced further labelling and other requirements, modified by CHIP2 in 1994.
