Abstract

PURPOSE:To obtain a glass product free from bubbles, foreign matter, cord striae, stripes, etc. by setting electrodes in molten glass at its upper position in the region of a hot spot section and supplying a current to increase the convections of the glass. CONSTITUTION:4-8 electrodes 16, 17 of 30cm or more in length such as molybdenum electrodes or tin oxide electrodes are set in molten glass in the region of hot spot section 9 of glass melting furnace 2 at a position of 1/20-1/2 of the glass depth from the glass surface by being inserted from the side wall of furnace 2 at an angle of elevation of 0-15 deg.. A current is then supplied to electrodes 16, 17 to form supplementary streams 18, thereby increasing radial streams 12, 14, 15 in a surface layer of the molten glass in the vicinity of section 9.
