Dissolution of the copper core from the hollow jewellery




Hi, In my company I'm trying to change hollow jewelry making process. Now we're trying to do hollow sample with copper core material. For dissolution of the core (pure copper) we're now thinking use electrolytically with sulfuric acid. If anyone knows something about these processes, please advise?

Hi, Senay. To my knowledge, hollow jewelry is done by electroforming gold onto wax. It is perhaps not impossible to plate onto copper and then dissolve the copper, but what advantage does this offer for all the extra effort and metal pollution?

Regards,
