We had a demonstration of another glass technique- making a sand mold. There was a large box of sand, which we would sift to created a loose packed consistency. The object that would be the original shape for the sculpture was then pressed down into the loose sand to make a tightly packed impression. The next step is what was shown here- applying a blowtorch all over the molded area, leaving a layer of carbon on the surface. The last step would be to pour in some molten glass. Once the piece had stabilized, it could be removed and cooled like any other piece.
