Abstract
455,751. Strengthening glassware. CORNING GLASS WORKS, Walnut Street, Corning, New York, U.S.A.-(Assignees of Phillips, C. J.; 78, John Street, Corning, New York, U.S.A.) Jan. 17, 1936, No. 1600. Convention date, Feb. 11, 1935. [Class 56] Glass articles are strengthened by tempering and, in addition, by fortifying the surface by submitting the article to the action of an etching agent which removes or smooths surface imperfections such as scratches. The glass may be heated to a temperature of 750‹ C., and then placed in a molten mixture of sodium hydroxide and potassium hydroxide, also at a temperature of 750‹ C. After a short time, the glass is removed and chilled rapidly. In another method, the glass is first subjected to an etching agent, such as hydrofluoric acid, and immediately after removal from the acid it is heated and chilled as in the usual processes for tempering. In a further method, the glass is first heated to the required temperature, then it is submerged in a chilling-bath composed of a molten mixture of sodium and potassium hydroxides at 650‹ C., and finally it is removed to another chilling-bath at a lower temperature. The glass may also be heated in a bath of the etching material and may be chilled in another. Other molten mixtures of salts which are strongly alkaline, such as alkali cyanides or carbonates, can be used instead of those mentioned above.
