Basic copper carbonate Wikipedia

Basic copper carbonate is a chemical compound, more properly called copper(II) carbonate hydroxide.It is an ionic compound (a salt) consisting of the ions copper(II) Cu 2+, carbonate CO 2− 3, and hydroxide OH −. The name most commonly refers to the compound with formula Cu 2 CO 3 (OH) 2.It is a green crystalline solid that occurs in nature as the mineral malachite.

Copper carbonate for granulation Jewelry Discussion

Dear Orchidians, I am just returning to gold granulation after a lapse of many years and have read of the use of copper carbonate as an additive to the hide glue, distilled water and flux mix. The problem is that I can’t find any formulas to tell me how much copper carbonate to add to this mixture. Anyone out ther e know and would care to share? I would be very grateful for any help. Thanks
