This isn't the final answer, but it is a clue:\n\nhttp://www.thesheetmetalshop.com/pdf_manual/Problem1.pdf

it depends on the material, you could have FCC, BCC, HCP and many other crystal structures, with many different substances present dependent on the alloy

In a single hand, there are 5 phalanges, and 5 meta phalanges. \n\nI hope this helps!

“Making your own Crystals”\n\nA crystal is a special kind of rock. Different crystals have different beautiful shapes and colors. \n\nWhat you'll need\n\n Your magnifying glass \n Table salt \n Epsom salt \n Honey jar \n Measuring cups and spoons \n Paper cut into circles \n Scissors \n Pencil \n String \n 1 3/4 cups of sugar \n 2 or 3 paper clips \n A glass jar or drinking glass \n Your science journal\n\nWhat to do\n\n \n\n1. Use your magnifying glass to look for crystals. Inspect: \n1. The table salt and Epsom salt; \n\nThe honey jar (particularly if it has been open for awhile) and \n\nThe walls of the freezer (if it's not the frost-free kind). \n\n1. Draw pictures of what you see in your science journal. \n1. Do all of the crystals look the same? \n1. If not, how are they different? \n1. Try dissolving salt crystals and forming new ones: \n1. Dissolve 1 teaspoon of salt in 1 cup of water\n1. Grown-up alert! \n\nHeat the mixture over a low flame to evaporate the water. \n\nWhat's left? \n\nWhat shape are these crystals? \n\n1. Snowflakes are made of ice crystals and are beautiful, but they are hard to see clearly. You can make paper snowflakes. \n1. Take a circle of paper (use thin paper) and fold it in half. Then fan fold it. \nMake cuts along all the edges. Unfold them. \n1. Grow rock candy crystals from dissolved sugar. \n\nGrown-up alert! \n\nPour a cup of boiling water into a dish and add 1 3/4 cups of sugar. Stir until the sugar is completely dissolved. Prepare a jar or glass as shown. \n\n\n\nWash the paper clips and use clean string. When the sugar water is cool, pour it into the jar and put it where no one will move it. Hang the paperclips in the water and put the pencil on top of the jar. \n\nSome crystals may form in a few hours. Some may grow to be half an inch on each side. To save them, take them out of the water and keep them dry. But they may disappear--they are good to eat. \n\nWhen certain liquids and gases cool and lose water, crystals are formed. Crystals are made up of molecules that fit neatly together in an orderly package. All crystals of the same material have the same shape, regardless of the size.

Here is a nice experiment to try.\nhttp://www.angelfire.com/mo/sasschool/DKScieMatter10.html\n\n"This tasty crystal making experiment is a great way to see the formation of crystals almost right in front of your eyes."\n\nAnother one.\nhttp://homeschooling.gomilpitas.com/explore/crystals.htm\n\n"Crystal Ornament"\n\nAnother.\nhttp://www.yesmag.bc.ca/projects/crystal_gardens.html\n\n"Crystal Gardens"\n\nOne for microscopic crystals.\nhttp://www.science.uwaterloo.ca/earth/waton/crystal.html\n\n"Crystal growing made easy"

Gem stones and crystals come in very many forms, with names ranging from Achroite to Zoisite.  The site below should give you an idea as to how many there are:

Use as much as you want.  The best way to grow these crystals is to disolve sugar into about a cup of water over low heat.  keep adding sugar until no more will dissolve (this can go on for a while so be prepared).  You could just do a cup of sugar if you like.  \n\nThen let it cool and set the water somewhere it will not be disturbed but has indoor temps to sit in. \n\nWait for a while to all of the fluid is gone and you will have your crystals.

Here are some potential sources:\n\nhttp://www.bestcrystals.com/ulexite.htm\n\nhttp://www.northwestnatureshop.com/department/Rocks_and_Minerals/Rock_and_Mineral_Specimens/592.html\n\nI'm sure you could find more if you googled it like I did.

boundaries between crystal grains are less well defined than the actual crystals, and have a different refractory index or optical density.\n\nIn anisotropic crystals, the refractory index or the surface structure of a transparent cut also depends on the orientation of the crystal.

10 percoset should do the trick\nThis is a joke....just in case you are dumb enough to try it.lol

There are 880, up to reflections and rotations. Check out the bit near the bottom of the webpage below.

As I said on the other question Piazo crystals are banged together.

Within your 3x3x3 cube, we have ten classes of rectangular prisms, including the two boundary cases of the whole cube and of the single cublet:\n1x1x1, 1x1x2, 1x2x2, 1x1x3, 1x2x3, 2x2x2, 2x2x3, 1x3x3, 2x3x3, 3x3x3.\n\nFor each prism class, we have to count all possible arrangements within the main cube. The contributes to this number are from translations, then from rotations (but only for non-symmetric prisms). If I'm not wrong, they are:\n1x1x1: 27\n1x1x2: 54\n1x2x2: 12\n1x1x3: 27\n1x2x3: 18\n2x2x2: 8\n1x3x3: 9\n2x2x3: 12\n2x3x3: 6\n3x3x3: 1\n\nTotal=174 prisms\n\nAs per your later addition, if we want to discard cubic prisms, we have: 174-27-8-1 = 138 non-cubic prisms.

Well depends on the amount of crystals you want, but yes you can. In fact I did it my self and obtained a few crystals.
