KEEPING RECORDS- LABORATORY
NOTES:
It is impo~lantto keepa record of eachprocedureyou perform.Usea small
notebook and pencil to record the important information about each
operation ORyou mayuse the record keeping log at the end of each
procedure.
The informabonyou should record is:
1. Timeand date you stad eachcrystal growing procedure.
2. Timeand date you end each crystal growing procedure.
3. Whatsize rock andwhattype rock usedfor the "baserock" for your crystal
growing procedure.
4. The nameof the chemical used, how muchchemical used, and how
nmchwater used in each crystal growing procedure.
5. Recordthe room temperature and the solution temperature dt the
beginningof each crystal growingprocedure.
6. Comments:
Note also whenyou could first see crystals beginning to
grow, whatShapethey are, and howfast they appearto grow. Noteif the
"baserocks" yo~are using are light or dark colored andwhatkind of rock
is usedfor "baserocks" (like limestone,granite, etc.). Youmaywishto use
the "record keeping log" printed at the end of each procedure.The most
important techniqueto developis to measure
all chemicalsandall amounts
of water VERYCAREFULLY.
For each crystal growing experiment, the
amountof water neededis given in gramsandmilliliters (ml) as well as
cups, teaspoonsand tablespoons. Youmayuse any system you like, but
the metric measurement
in milliliters (ml) or grams(g) will be usedin
manual. The size "D" crystal growing cups have two markings embossed
on them.The lower markdenoting20 mililiter (ml) andthe upperdenoting

that are usedin the
following experiments.

crystal system.
Crystals of the samechemicalsubstancemayexhibit a wide variety of shapes. However,it is possible to choosethree
reference axes (called crystallographic axes) that uniquelydefine the geometryof each crystal. Theseaxes intersect at
common
point at the center of the crystal. For highly regular shapeslike cubes(high symmetry),the axes are the samelength,
and the angles betweenthe axes are 90°. Anexampleof this type of crystal is table salt (the mineralhalite). Thereare seven
different combinationsof crystallographic axes. Theseare called crystal systemsand are shownin the marginimmediately
below. The"GoldenCitrine" crystals that you will growin Procedure#1 crystallize in one of these systems. Canyou determine

"Aquamarine
Blue"
Crystals
The actual gem AQUAMARINE
is a color variation
of the mineral crystal beryl. Eme--alds are also beryls. Both
aquamarine and emeralds are classified in the hexagonal crystal system. In Procedure #7 you will grow a blue chemical crystal
which only simulates actual aquamarine in color and crystalline appearance. Your blue crystal clusters are formed in a water
(aqueous) soi,~tion
of monoammoniumphosphate which contains atoms of nitrogen, oxygen, hydrogen and phosphorous.
Actual aquamarine is formed under extreme pressure and heat over long periods of time. Actual aquamarine beryl is made
of atoms of beryllium, aluminum, silicon and oxygen. Both actual aquamarine and your chemically grown "Aquamarine Blue"
crystals form in the hexagonal crystal system.
Sometimes you may obtain needle-like crystals from your crystal growing experiments. Other conditions may produce
prismatic crystals. The difference maybe due to conditions of temperature or humidity, or to the in,purities given to the solution
by the "base rocks" that you use. Similar differences in crystal shape occur in nature because atorr s in the solution surrounding
the growing crystal are attracted more strongly to some surfaces (faces) than others. This means that different crystal faces
grow at different rates - the slower the rate of growth, the larger the face. Whenan impurity atora attaches itself to a growing
surface, it may alter the rate of growth of a particular face, and change the shape or "habit" of the crystal (needle-like to
prismatic, for example).

"EmeraldGreen~Crystals
Natural emeraldis a green variety of beryl. It is one of the mosthighly prized of all gems.Emeraldshavebeen knownfromthe time of
the Greeks,and wereminedin Egyptas early as 2000B.C. Crystals of emeraldare smaller than other beryl gemssuch as aquamarine(bluegreen), whichis one reason whylarge emeraldsare so valuable. Emeraldsdo not crystallize fromhot chemicalsolutions, as do the other
beryls, but growin solid rock as the temperatureand pressure increases. All beryls belongto the hexagonalcrystal system,and commonly
showsix-sided shapes called prisms. The deepgreen color in emeraldis due to the replacementof aluminum
by small amountsof chromium
during growthof the crystal. Naturalemeraldcontains inclusions of foreign materials that can be usedto distinguishit fromthe synthetic
gem.Theseinclusions, whichare trapped inside the crystal as it grows, can sometimesbe used to determinethe exact place wherethe
emeraldwas "found. The "EmeraldGreen"crystal clusters whichyou will growin Procedure#8 are, of course, not real emeralds. Your
chemical crystals are grownfrom a water (aqueous) solution containing monoammonium
phosphate and a green dye. Your chemically
growncrystals only simulate the color of real emeralds. Nonetheless,you will enjoy the beautiful shape (hexagonalsystem)and color
variations of your own"EmeraldGreen"crystals.

TROUBLESHOOTING:
WHATIF MY CRYSTALSDON’T GROW?
After completing all of the procedures, you should now
havea collection of various crystal specimens
of different
crystalline shapesand colors.
Youwill also havean assortmentof "saved"residuechemical solutions and residue crystals. You mayexperiment
with these to try and grow your own crystals. Youmay
experimentwith growinglarge single crystals or with growing clusters of crystals. Youmayalso wantto try to grow
multi-coloredcrystals by first growinga crystal cluster of
one color and then changingthe solutions to havethe final
growthof thosecrystals of a different color.
For example:if you use the chemicalsfrom the "Aquamarine Blue" crystal procedureas well as colored chemicals
from the "Golden Citrine" and "Emerald Green" proceo
dures, what kind of results can you obtain?
You have seen that by evaporating solutions you can
concentrate the growing solutions to makethe crystal
growths larger. Remember,
whenevaporation happensin
a solution, the chemicalsremainin the solution andonly the
water evaporates.
Try experiments of your owndesign, evaporating small
amounts of various saved solutions and describe the
results.
Onall of the experiments
whichyoutry on your own,be sure
to keepdetailed notesso that if youdiscovera newcrystal
you can reproduceyour results again.
If crystals do not grow properly there can be several
reasons.If no growthis observed,you haveprobably used
too muchwater. If this is the case,just remove
the solution
andre-boil it in a stainless steel or Teflon® coatedsaucepan or in a non-aluminumsaucepanwhich is no longer
usedfor cooking.Let the solution cool andpourit backinto
the crystal growingcup. If youusetoo little water, youmay
get manyvery small crystals. In this case, simplyadda bit
morewater to your growingsolution, reheatit, cool it, and
addit backto your crystal growingcup.
Sometimes
the type of "base rocks" which are used will
hinder the growthof crystals. Some"baserocks" seemnot
to accept crystals growing on them. You will have to
experimentwith what type of "base rock" worksbest with
your different procedures.
Alwaystry to keepgoodrecords, and carefully measureall
chemicalsand water to makeyour solutions.
The temperature in the roomwhich you select for your
crystal growingis an important factor. The temperature
should remainfairly constantand unchanging.Humidityin
the air also will causechangesin crystal growth.Humidity
affects howfast the solutions will evaporateand therefore
howlong it will take for somecrystals to grow.
Whilecrystals are growing,try not to disturb them.Youmay
useyourflashlight to obsor’.~etheir growth,but tP) to doso
without disturbing the crystal growingcup.
