For growing a beautiful crystal of the correct form, clean solution. To prepare it you need: distilled or boiled water, chemical glassware for solution preparation, laboratory filter that can be replaced with a blotter or cotton wool, a clean sheet of paper.
To the crystal grew large and beautiful takes a lot of time. This is a complex and lengthy process that requires caution and patience. First you have to prepare small crystal – seed. As soon as the first crystals, you must choose those who have the most correct form or which you like best.
Beaker, fill half with warm water and add small portions of salt. Stir the solution after each portion of matter. As soon as it ceases to dissolve, all again carefully mix.

You should look out for, so that upon evaporation of the solution the upper part of the crystal was not in the air. It'll ruin him. That this did not happen, add the solution into the tank as needed.
In the process of growth of the main crystal in the solution can appear and grow other crystals that need to be removed at least once in two weeks.
Filter the solution using best laboratory filter, but if not, then you can use the blotter or cotton wool. Than it is denser, so will be cleaner liquid.
