Cultivation of crystals from copper vitriol directly at home - it is simple. For this purpose special chemical skills will not be necessary, and you will be able to make everything by means of make-shifts.
It is required to you
- - measured flask of 0.5 liters;
- - chemically raw water (from under the crane);
- - powder of copper vitriol;
- - tile or other device for heating of capacity;
- - thread;
- - needle.
Instruction
1. For cultivation of crystals take the measured capacity of 0.5 liters (on which capacity is divisions in milliliters) and fill with chemically raw water on 300 milliliters, and later put on an electric tile.
2. Further powder of copper vitriol (oxide of copper of blue color) is required, it can be got in any shops for gardeners. Pour out 200 milliliters of copper vitriol in capacity and mix when heating water to full dissolution.
3. Remove capacity from a tile and let's the turned-out solution cool down, and then it is necessary to choose an average piece of copper vitriol. Such that he could be tied a thread – it is necessary for creation of "bait". Tie to one party of a thread the chosen piece, and other party of thread - to a subject which will hold a piece of vitriol in capacity in hover (for example, a needle), and lower "bait" in solution.
4. After a while on a thread small crystals will begin to be formed, but the bulk of copper vitriol will remain at the bottom. Further put capacity on a tile again and heat to dissolution of a deposit. After that cover capacity and let's solution be cooled.
5. Now lower in solution a thread with crystals, cover capacity and leave in such situation approximately for 12 hours. After past tense on a thread the many-sided crystal of blue color is formed.
