Theyare made of metal, and are used as patterns from which to makedies or molds, as may be required, for the swaging of gold cuspsor crowns. There is, therefore, no wear upon them, and they re-tain their shapes and sizes unaltered. The outfit for working these forms consists of a molding-plate,three rubber rings, a sheet of asbestos, 10 X 7 inches, and a carbonstick for use in casting. Fig. 577. Fig. Fig. 578.
