I have a concept for an enameled piece that involves enameling on
gold plated copper. While researching my process, I was unable to
confirm that plated gold will withstand enameling temperatures.
I didn't see your entire post (just a couple of posts), but I would
suggest enameling on the copper, then have your piecce gold plated.
When silver and gold foils are used on top of copper, one must put
down a layer of flux between the two metals to prevent them from
creating an alloy when heated in the kiln. Otherwise you end up with
ugly puddles of metal which could be cool if that is what you wanted
in your design. Tom Ellis from Thompson Enamel
