Was wondering if anyone has advice on enamel on copper. Annealing
temp for copper and firing temp for enamel are similar, so if I need
to tumble the piece after enamelling to work harden the copper
(enamel is an accent, n ot covering the surface), is there any
danger to the enamel? And if so, is there a way to protect it, and/or
any other way I’m not familiar with ? Any help much appreciated!
