Abstract
A molten glass recirculating apparatus is provided, comprising a riser chamber having a first opening positioned below a molten glass level and a second opening positioned above a molten glass level, a trough positioned adjacent the upper opening, and a gas emitter positioned within the riser chamber below a molten glass level and methods of using the same. When a gas is emitted from the gas emitter, molten glass contained within the riser chamber rises and exits the riser chamber through the second opening and along the trough. The exiting molten glass causes additional molten glass to be drawn into the riser chamber through the first opening. The invention also comprises a glass melter including a plurality of glass recirculating means, each being individually controllable to control the circulation of molten glass within a glass melter.
