ABSTRACT:
A furnace for fining molten glass is provided in which glass flows in a substantially vertical direction prior to exiting the furnace. As it flows vertically, the glass is allowed to cool. This cooling, in turn, allows the glass to be removed from the furnace through a narrow passageway without producing excessive wear of the passageway. Preferably, vertical flow of the molten glass at the exit end of the furnace is produced across the furnace's full width. In this way, the molten glass does not stagnate within the furnace and undesirable scums on the top surface of the glass are avoided. In certain preferred embodiments, the vertical flow is achieved by a trough which has sloped sides and which connects with and extends downward from the bottom surface of the furnace.
