I want to cast a mold of small doll faces so that I can use them to make sculpy faces. I'll be using a piece of metal jewelry, a metal door knocker, a small plastic doll and possibly some ceramic dolls.
If I press a lump of sculpy onto these things to make the imprint will I be able to use the baked sculpy mold to make sculpy reproductions? Will the soft clay just stick to the baked clay? Should I paint it with a varnish of some sort to make it less sticky?
Is there something else i should be using for this idea instead of clay?
Thanks so much!
