Thanks all. Corey the sculpt is still intact, so remolding will only require some minor touch up work and a little reshaping from where I removed the silicone mold and pulled on a couple areas.. I used Monster Clay for the first time on this sclupt. It's not the easiest to work with, but overall I'm happy with it. Yes, as answered above, stone molding is simply plaster molding using Ultra-cal or similar. I'll post up a latex pull soon.
