Hello Mary Rose,
if you have the possibility to lent the book: "Experimental Techniques in Enameling" by Fred Ball, you'll find some other possibilities to use copper and othet metal foils

In the Notebook #2 under Metallsmith techniques you find a file re the use of copper foil. Here is the Link:

I am interested in enameling on thin copper. Has anyone had experience with this and how thin was the copper? And what type of enameling did you do?
Thank you, Mary Rose
