Doug,
The primary mold was made with regular set alginate from Artmolds and burlap strips dipped in lab dental plaster. I then cast the face with regular dental plaster. After the cast had dried and repairs had been made, I made a skin mold with RTV silicone from Polytek and the mother mold was made using Forton MG. To create the mask, I pressed the clay into the silicone rubber mold to a thickness of about one inch (a bit thicker in center of the face). I let it dry for about a week and then made final repairs (the clay shrinks) to the mask before the final drying and firing.
Piece of cake, huh?
