Abstract

A process for producing a glass in which an excessive vacuum is prevented from enlarging a bubble layer and thereby reducing the effect of vacuum degassing; and a vacuum degassing apparatus suitable for use in the process for glass production. The process for glass production includes a step in which a molten glass is degassed under vacuum in a vacuum degassing tank. It is characterized by forming at least one gas stream over the molten glass passing through the vacuum degassing tank, the gas stream being selected from the group consisting of a gas stream in the flow direction for the molten glass and a gas stream in the direction opposite to the flow direction for the molten glass.
