I have a baked Sculpey model which I want to make a plaster mould out of, so that I can then use that mould for casting clay replicas of the original piece. The model itself is pretty simple and has a flat back, and so I can make a one piece mould by just pouring the plaster on top of it.
What I’m struggling to find any advice on is what mould release to use to stop the original model stick to the mould, but without affecting the absorbency of the plaster so it will still dry out clay well when I come to cast from it. Anyone got any suggestions on what to use?
Thanks!
