Guide
1
The first step is the preparation of a concentrated composition of copper sulfate.We must take the flask with water, put in her vitriol and mix gently.To understand when the salt solution is sufficient, it is necessary to watch closely, as it dissolves.If dissolution is no longer to occur, immediately stop the dilution.At three hundred grams of water usually have two hundred grams of vitriol.
2
Then take a pot, fill it with water (not to the brim) and put back the glass.The goal - a few warm-up, but no more.Watch carefully and stir.Should a concentrated lukewarm solution in which managed to dissolve all the vitriol.
3
Take a jar or cup and pour dedicated to the resulting liquid.Now we need to prepare so-called "seed."To do this, take a string and tie it to a small crystal of copper sulfate.Make perekladinku to secure the thread and put it on a glass, dropping a crystal in a solution.The solution should have time to time to cool slightly.
4
around this thread and will grow a crystal.Initially attached crystal dissolve - it does not matter.Next two ways: either grow a crystal quickly or slowly.In the second case, it is important to take the seed for a beautiful crystal (to get the same, only bigger).In this case it is necessary to remove the structure from the veiled banks perekladinki and thread in a secluded place, where there will be room temperature.And wait.About two weeks.Then enjoy the results.
5
If you want quick results, you need a solution again heated slightly lower thread again and something to cover bank.And then several times - from mild heating to cooling.Watch - a thread, when the solution is cooled down, the other will attach small crystals.If the result is a small pellet, it's okay.Hide the bank on the day.One day a handsome crystal is ready.
Note

- You can make a crystal of unusual shape - to wind the wire in a specific shape (eg, heart-shaped), and make sure that the crystal is nottoo grown to outlines were visible
