Abstract
650,219. Glass smelting by electric heating. GALLOIS, R. Dec. 29,1948, No. 33430. Convention date, Jan. 13. [Class 39(iii)] A process for melting a glass batch in three consecutive stages consists in first heating the batch by electrical resistances to render it electrically conductive, in then heating it by the passage of electric current therethrough until a temperature is reached at which all endothermic reactions are completed, and then melting and refining the glass in a separate tank as by the passage of current therethrough. The temperature attained in the first stage is about 400 to 600‹C. and in the second stage about 1000‹C. The second stage is preferably carried out in a heat-insulated tank having two of its opposite faces constituted by electrodes between which the voltage gradient does not exceed 100 volts A.C. per centimeter. This latter tank may be of vitreous silica and the electrodes of metal or grasilica and the electrodes of metal or graphite.
