Abstract

A process and an apparatus for refining molten glass by introducing, a stream of unrefined molten glass into a controlled environment distributing the stream of molten glass over a flow surface, and collecting the stream of molten glass from a downstream end of the flow surface to form a body of molten glass having a free surface exposed to the controlled environment. The controlled environment, may have a pressure less than ambient atmospheric pressure, such that introducing the stream of molten glass into the controlled environment causes gaseous inclusions in the stream of molten glass to rise to a surface thereof and escape.
