Ok so. I make dragons and I've been dying to find a method where I can make them with one material. So I made my molds one out of fiber glass and one from plaster both are two part molds. I filled them With foam latex from monster makers and closed them. And baked them at 160 degrees for 4hrs. both turned out good at the bottom and spongey and moist on the top layer.
any advice would be awesome. Maybe I'm not using enough foam ? it seems to evaporate on one side. I live in Florida and use a small smoker with a heating unit.
