Abstract
A method of producing glass includes receiving unrefined molten glass in a stilling chamber of a stilling tank at a fluctuating flow rate. An intermediate pool of molten glass is held within the stilling chamber of the stilling tank and is heated therein by one or more non-submerged burners. Molten glass flows from the intermediate pool of molten glass to a transfer pool of molten glass held in a spout chamber of a feeding spout that is appended to the stilling tank. A molten glass feed can be drawn from the transfer pool of molten glass and delivered from the feeding spout at a controlled flow rate.
