The process is pretty minimalist and straightforward. The materials include:

  • Copper sulfate
  • Water
  • Jar
  • Gloves

Step two: Saturate the Copper Crystals.

Step three: Place the Solution in an Undisturbed Location

After some time, you should notice crystals forming at the bottom or on the walls of the glass jar. You can proceed to pick out the perfectly formed crystals.

They say good things take time, and so do beautiful crystals. You will need to be more patient if you want larger crystals.

Typically, the process should take a while as the solution evaporates slowly and the excess crystals combine to form gorgeous single pieces.

Throughout the period, the temperature changes should be as minimal as possible since that will likely disrupt the formation.

Therefore, it is advisable to place the jar of saturated solution in a room exhibiting negligible temperature shifts.

As your crystals grow, you may also notice many tiny crystals forming.

To aid the process, you can remove the larger crystals from the solution, decant the solution into another jar and place your more giant crystals back within the shortest period to avoid any interruptions in growth.

It is crucial to remove the smaller crystals as they are likely to compete with the larger ones.
