I am doing a piece of plique a jour piece ( like stained glass) with
a very undulating shape. So i can’t use a plain copper retaining wall
fixdture to hold the enamel in while firing and I will have to mold
it and cast it.
The problem is that copper doesn’t cast well. Is there another metal
that I can cast and etch away without harming the gold? Or maybe
you have other ideas as to how to do this? Thank You, John
