I feel so bad that I am always asking questions, but not yet experienced enough to answer many!!! I am just starting to send my wax designs to a casting house. I want to enamel parts of the pieces after. They don't cast in copper, and sterling silver is too expensive to do all of my pieces in. So I was thinking of doing brass and having it gold plated. They offer a service of plating in 9k gold. Can I enamel on this? I can't seem to find an answer anywhere on the web. I see some jewelry companies out there offer brass or gold plated brass enamel jewelry, and it baffles me how they do it. I have been told enamel will just pop off of brass.
