Abstract
Controlling the level of molten material in a melting furnace is disclosed. The level of molten material is sensed downstream of the furnace and batch materials are choke fed to keep the total batch crust plus molten glass depth constant. This provides for simpler molten glass level control as melter power can be directly controlled in response to glass level.
