Abstract
The improved joule effect glass melt apparatus and method of using the apparatus delivers isothermal glass to a glass forming bushing and reduces the erosion of refractory at high melt temperatures by isolating the refractory from joule effect currents. The glass melt apparatus uses molybdenum liners located on the side walls of the molten glass receptacle to receive joule effect current and provide a uniform temperature distribution through the glass. A molybdenum flow block and molybdenum heat sink located in the flow block complete the heat distribution in the molten glass, achieving an essentially isothermal cross section molten glass upon arrival at the glass forming apparatus or bushing.
