Crystals are solid bodies, molecules or atoms which form crystal grid. It is possible to grow up them by means of process of crystallization of solutions, vapors or fusions which begins under certain conditions, for example, glut of steam, liquid overcooling.
It is required to you
- - the distilled or boiled water;
- - chemical ware for mixing of mortar;
- - the laboratory filter which can be replaced with blotter or cotton wool;
- - clean sheet of paper.
Instruction
1. For cultivation of beautiful crystal of the correct form, pure solution is necessary. That to prepare it will be required: the distilled or boiled water, chemical ware for mixing of mortar, the laboratory filter which can be replaced with blotter or cotton wool, clean sheet of paper.
2. That the crystal has grown big and beautiful, a lot of time is required. It is difficult and long process which demands care and patience. At first it is necessary to prepare the small chip – priming. As soon as there are first chips it is necessary to choose from them those which have the most regular shape or most of which of all are pleasant.
3. Fill chemical glass half with warm water and add in the small portions salt. Mix solution after every portion of substance. As soon as it ceases to be dissolved, still carefully stir time. Filter the prepared solution in other glass where the crystal will grow, and cover it with paper. In week the crystal considerably will grow up.
4. It is necessary to look after that at solution evaporation the upper part of crystal has not appeared on air. It will spoil it. That it has not occurred, add solution to capacity as required.
