Sensei Posted November 12, 2015 Share Posted November 12, 2015 (edited) My new crystals... I just yesterday noticed how they grew up. They were growing up 4-5 months at least. I set up beaker in June-July 2015. The largest one has 3 cm +-. Edited November 12, 2015 by Sensei Link to comment Share on other sites More sharing options...

Klaynos Posted November 13, 2015 Share Posted November 13, 2015 I'd guess copper sulfate. Link to comment Share on other sites More sharing options...
Sensei Posted November 14, 2015 Author Share Posted November 14, 2015 If it would be Copper Sulfate dissolved in water, and reduced, what would be doing this piece of metallic Copper inside of flask? I would have to have Sulfuric acid initially in flask. Link to comment Share on other sites More sharing options...

I would have to have Sulfuric acid initially in flask. For some reason I completely ignored the big lump of copper. Link to comment Share on other sites More sharing options...
