METHOD FOR FORMING A GLASS ARTICLE

A method of manufacturing a glass article includes flowing molten glass through a first vessel to a downstream second vessel, the molten glass flowing through a conduit connecting the first vessel to the second vessel, the first vessel and the conduit defining a continuous free volume above a free surface of the molten glass extending into at least a portion of the conduit. The method further includes venting a first atmosphere contained in the free volume to a second atmosphere external to the first vessel through a vent tube connected to the conduit proximate a top of the conduit and above the free surface, the vent tube extending downward from the conduit to a distal end of the vent tube along a longitudinal axis at an angle a relative to horizontal and providing fluid communication between the first atmosphere and the second atmosphere.
