These are formed by pressure and a 100 Ton press. These are wonderful for doing Cloisonne. 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. I have even sanded the edge for you so it is nice and straight. 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,
