ABSTRACT:
A curtain of reducing gas is established across the entrance end of a glass forming chamber which employs a pool of molten metal to support glass during forming in order to impinge reducing gas along a line across a refractory delivery piece and molten metal region of the forming chamber in order to insure that molten glass is initially delivered onto molten tin free of contaminants, such as metal oxide.
