i want to make copper sulphate crystals but i dont know where to start?

Answer 1

Instead of giving you long answers, I decided to give you links to crystal growth labs and activities - for more than just copper sulfate.

Alum OR copper sulfate:

How to make a saturated solution, and more details, including other ideas for crystal growth::

LOTS of crystals...

Happy growing!

Answer 2

Answer above basically right - just a few more details. Dissolve as much as you can in about a quart of warm water, stirring to assist. Use bottled distilled water - minerals in normal tap water can upset crystal growth. Put the liquid in a pan on the stove and heat to just below boiling. Add more sulfate, a little at a time, stirring as you do. When no more goes into solution, remove from heat and transfer to a glass jar - a wide-mouth quart jar used for home canning is perfect. Allow to cool. Find a length of clear fishing line. Tie one end around a rod or stick (a pencil works great) and cut the end so that if the pencil is placed across the mouth of the jar, the line would hang down a little more than two thirds of the way to the bottom of the jar. Tie a knot at the end of the line around the smallest piece of metal you can find so that the knot is 2/3 of the way down. The metal weights the line down so it stays in one place and acts as a seed point for crystals. Put some place where the jar will not be disturbed or moved but where you can see it. Lower the pencil/line down into the solution and let the pencil rest on the lip.

That's it. The water will start to evaporate and the excess sulfate will drop out of solution and a crystal will start to grow. Some of them get pretty big. You can adjust to pint jars or go the other way and try larger quantities.

Good luck.

Answer 3

you can get copper sulphate at most pool cleaning shops, you then need to dissolve as much as you can in water till it is saturated. then super saturate it by dissolving more into the water wile heating it then just hang something in the solution and as it starts to cool crystals will form.
