Abstract
477,585. Tempering glass. CORNING GLASS WORKS. June 30, 1936, No. 18166. Convention date, July 31, 1935. [Class 56] A process for tempering glassware consists in using a bath of molten inorganic salt or salts for heating or chilling the articles, or both, the molten salt being inert to the glass and having a low vapour pressure at the temperature to which the glass is heated. A mixture of sodium sulphate and potassium chloride may be used for the heating bath, and a eutectic mixture of sodium nitrate and potassium nitrate may be used for the chilling bath. Other suitable compositions are given in the Specification.
