To grind glass, a material of low tensile strength must be used. In this instance silicon carbide abrasive stays sharp longer, and on hardened steel, a material of high tensile strength, aluminium oxide abrasive stays sharp longer. Therefore each abrasive works best when it is suited to the grinding operation.
