Abstract
731,405. Melting glass by passage of current. ZEISS-STIFTUNG, C., [trading as JENAER GLASWERK SCHOTT & GEN.]. May 26, 1953 [June 6, 1952], No. 14602/53. Class 39 (3). In melting glass by passing current therethrough between electrodes in contact with the glass, the current is supplied at a frequency of at least 2000, 4000 or 7000 cycles per second, in order to prevent a colloidal atomization of the electrode. The electrodes are of platinum, molybdenum or tungsten and may have small surfaces, the density of the current supplied being at least 10 amperes per sq. cm. The lowest electrode may be of liquid tin. An electrode may comprise a thin layer of platinum or of a noble metal chemically related therewith on an insulated bracket, e.g. a ceramic rod or a tubular socket. The electrodes may be continuously moved in the glass, or the glass is passed continuously over the electrodes by a stirrer. The electrodes may be cooled. The melting pot may be of platinum with a single tubular platinum electrode dipping therein, the heat generated by the resistance of the electrode serving also to melt the glass. Specification 684,911 is referred to.
