Unfortunately I've been making all of my originals in oil based clay (I've been using kiddy clay but I have some plasticine). So that leaves me with some more problems. I could use another original material such as water based clay. I'd like to stick to clay because I like the forgiveness of it. I could always make an alginate mold and then make a master cast out of hydrocal (I think I have some left) and use that to make a mold but then I'm making a copy of a copy. Might there be something I could coat the original with to make it happy with the RTV? I knew that learning about molds would help me down the line but I never thought I'd be casting tikis:)
