  • stock salt.Transparent crystals obtained from a simple salt.You can also get colored crystals: the bright blue of copper sulfate and purple from hromokalievyh alum.One can take, and other water-soluble salts, such as different colored alum.The amount of salt depends on its solubility in water.The more readily soluble salt, the more it required.
Guide
1
dissolved in a glass of water as much as possible the amount of salt you choose to grow a crystal.To do this, pour the salt in the water, stirring constantly, until the salt stops dissolving.
2
solubility of the salts is significantly increased when the temperature rises, so to get more intense the salt concentration in the solution, it n
eeds to be heated.To do this, a glass with a solution of salt in a pot of warm water, to get the effect of the water bath.With the gradual heating of a mixture of salt should be completely dissolved.
3
Now pour the solution into a jar or a glass of thick glass, and drop to the same crystal salt, tied on a string.Threads fix on a jumper wire.This crystal will act as a "primer" on which to settle the salt from the solution, gradually growing into a crystal.
4
glass with a salt solution put in a warm place.Now you need to be patient - do not move the vessel with a solution of a place, do not turn and do not lift it.Even a slight shake of the solution will lead to rapid crystallization and autonomous system.Within three days on a string appears crystal, which will gradually increase.
5
When your chip will be large enough to remove it from the solution, blot with a napkin, cut the excess thread.To the crystal has not disappeared in the air and will not warp, cover it with the edge clear colorless varnish.
