| abstract | 456,551. Treating glass surfaces. CORNING GLASS WORKS, Walnut Street, Corning, New York, U.S.A. Oct. 25, 1935, No. 29544. Convention date, Nov. 6, 1934. Addition to 455,460. [Class 56] [See also Group XL] Relates to a method of treating glass, described in the parent Specification, to prevent it from being discoloured by hot alkali vapour, when used, for example, as the envelope of a sodium vapour arc lamp. According to the present invention, the glass is coated with a solution containing salts which are converted, when the glass is heated to about 600‹ C., to a substantially transparent residue consisting of a mixture of boric oxide and an alkali fluoride. Specification 441,603 is referred to. The solution is atomized on to the warm glass, or the glass article is rinsed in the solution and dried, and the treated glass is then heated to about 600-650‹ C. Compositions of suitable solutions are given in the Specification. |
