Notes
A white nonmetallic, natural mineral identified chemically as calcium metasilicate, CaSiO3. It is used in ceramic wall and floor tile, in glazes, and in frits for glazes and enamels. It also finds use in glaze and body stains, in bonds for vitrified grinding wheels, in electrical insulators, and as an auxiliary flux. W-10 is 200 mesh, W-20 is 325 mesh, W-C-1 and DFSP are crushed.
