Hello,

I need to enamel a red transparent on a champlevé piece made of 10k white gold. There is a 12% nickel in the alloy composition of the white gold. Can anyone help me with this? I intend to use lead bearing enamel either Soyer or old Thompson enamel. I have never enameled on white gold before, should I expect any specific complication because of the nickel concentration?
I also don’t know if I need to use a flux (clear enamel) before and if so, what should I use?

Thank you,

Gabrielle
