Is there any way of colouring precious metal clay - either silver
or gold PMC? I suppose that simply mixing silver and gold PMC
wouldn’t work, because that just seems too obvious! But could you
mix in something like powdered niello? I would like to achieve a
kind of “mokume gane” effect, by kneading differently-coloured PMC
mixtures together, but I don’t know of any way of achieving a colour.
Has anyone tried something like this?
