Abstract

223,837. General Electric Co., Ltd., (Assignees of Patent Treuhand Ges. f³r Elektrische Gluhlampen). Jan. 24, 1924, [Convention date]. Enamels; enamelling.-Glasses or enamels having a low melting-point consist of a lead borate or lead borosilicate composed of a number of constituents in accordance with the following molecular composition :-PbO, 1.0; B2O3, 0.45 to 0.55; SiO2, o to 0.20; Al2O3, 0.04 to 0.20; Na2O, 0.04 to 0.07; K2O, 0.01 to 0.02; As2O3, 0 to 0.01; Co2 O3, 0 to 0.04. The Co2O3 may be replaced by other colouring or opacifying agents. The mixture fuses at a temperature below 400‹ C., generally between 360‹ and 400‹ C. These enamels are suitable for marking electric lamp bulbs, their low fusing-point preventing the thin glass bulbs from becoming deformed while the enamel is being burnt on. They are also suitable for use as an adhesive between metal, glass, porcelain and the like. They may be used, also, for coating metal or glass bodies by heating the bodies and dipping them whilst hot into the powdered enamel. Specification 28524/03 is referred to.
