ABSTRACT:
For the manufacture of formed parts made of glass, as for example, grill gratings or grease pans for kitchenstoves, a piece of plate glass that is cut to size is placed on a mold which corresponds to the shape of the desired piece of glass; and is heated. In order to prevent a premature lowering of the softening piece of plate glass, during the softening process, it is supported by a gas cushion.
