How can I made multiple plaster molds from one clay model?
I want to use a clay model and have it cast into a two part plaster of paris molds, so I can use it for papier mache.
My problem is, I want to have several identical molds of the original copy. I can't figure out how I can do this though, as I would have to pick to clay/plastercine out of the original mold. Has anyone got any ideas to get around this? I was thinking maybe I could make the first plaster mold, make a rubber copy of the model inside and then from there, make the other molds. Could this work?
Any help or advice would be brill,
