These are wonderful for doing Cloisonne or for whatever. We have annealed these with our torch and water quenched them to clean them, we also put these in acid to clean off any oxides that formed. This is one solid piece of copper, no soldering, it is formed by pure force by a 100 Ton Press. I have even sanded the edge very flat and clean for you.I feel these are a novel product, unknown to the trade, I have never seen copper Bezel Cups anywhere. These would be great for enameling or other applications. These are solid 1 piece of copper item, no soldering.
