ABSTRACT:
Removal of gas inclusions from a molten glass pool is enhanced by inserting a gas inclusion-permeable, refractory metallic or ceramic screen in the downstream flowing, upper portion of the pool, to diminish the glass flow rate adjacent the surface by viscous drag forces while permitting gas inclusions to rise through the screen to the surface of the molten glass pool to dissipate into the atmosphere therealong.
