I've seriously been thinking about buying a 5lb tub of monster clay but I have several questions about it. First, if I make a plaster mold, what kind of release agent would be needed if any. Second, if I used a release agent, would it somehow affect the composition of the monster clay? I'm wanting to use paper clay instead of latex for the finished project so I really don't know if this idea is even feasible at all. Any help at all will be appreciated.
