Rubber and Plaster Molds for Waxes

The Sculpture II students are learning how to make make two and three part molds of their original objects, so they can pull wax positives for lost-wax investment castings.  A few shots here show projects in various stages, from making the molds, to pulling the waxes, to spruing up the wax systems to be invested in a plaster/sand concoction.  Ultimately, these will be burned out and filled with bronze or aluminum at the metal foundry at West Virginia University.
