摘要
A method of reducing bubble lifetime on the free surface of a volume of molten glass contained within or flowing through a vessel including a free volume above the free surface, thereby minimizing re-entrainment of the bubbles back into the volume of molten glass and reducing the occurrence of blisters in finished glass products. The method includes vaporizing a volatile material, entraining the vapor in a carrier gas to form an enrichment gas, and flowing the enrichment gas into the free volume to increase a concentration of the volatile material at the surface of the molten glass in the vessel.
