A. The most common casting material for alginate molds is gypsum cement. Gypsum cement is chemically related to plaster but much, much stronger when fully cured. Our product LifeCAST is a high strength gypsum cement that is about 10 times as strong as Plaster of Paris when cured. Various silicones can be poured into alginate molds. Some people pour hot wax into them, chocolate can be used, and some folks work with fast setting Portland cement.
