Difficulty: Easy Time Required: a few days What You Need To Grow Copper Acetate Crystals copper acetate monohydratehot distilled wateracetic acid (if necessary) How To Grow Copper Acetate Crystals Dissolve 20 grams of copper acetate monohydrate in 200 ml of hot distilled water.If there is a scum of undissolved material, stir in a couple of drops of acetic acid.Cover the solution with a paper towel or coffer filter and allow it to cool in an undisturbed location.Blue-green crystals should start to spontaneously deposit within a couple of days. You can allow them to grow or can select one small crystal to use as a seed crystal to grow a larger single crystal.
