Abstract
A glass fining system, glass fining device, and method are disclosed. The glass fining device in accordance with one aspect of the disclosure includes at least one heated orifice through which molten glass flows from a glass melter to produce at least one superheated glass stream; and a low-pressure chamber disposed downstream from the heated orifice, where the at least one superheated glass stream flows from the at least one heated orifice and into the low-pressure chamber, and where the low-pressure chamber surrounds the at least one superheated glass stream. In some embodiments, the low-pressure chamber may include at least one surface extender.
