Zusammenfassung:This invention relates to a vacuum degassing vessel wherein even if bubbles of molten glass come into contact with an inner wall of an upper space of a vacuum degassing vessel to produce a molten glass flowing along the inner wall, a molten glass can be discharged to the outside of the vacuum degassing vessel, thereby performing vacuum degassing without deteriorating composition homogeneity of the molten glass.
