摘要： A method and apparatus for continuously melting and refining molten glass are disclosed which comprises the steps of applying a preponderance of heat to a molten glass mass by Joule effect heating and pulsating a portion of the heat applied to the molten glass mass such that the temperature of the surface molten glass is increased and the temperature of the molten glass being withdrawn is reduced and the total energy supplied to the furnace is reduced. An electric circuit means comprising at least two interconnected electrodes is pulsated on and off at predetermined time intervals in order to establish the desired temperature profile within the molten glass mass.

摘要： The present invention is an auxiliary heated bushing block for a fiber forming furnace. The bushing block fits below an opening in the bottom of a forehearth of a glass melting furnace. A non-circular opening through the bushing block allows molten material to flow into a fiber forming bushing. Electrical resistance heater elements protrude through the ends of the bushing block into the non-circular opening into contact with the molten material. Each electrical resistance heater element has associated with it a separate adjustable power supply to provide individually variable power to each electrical resistance heater element. By varying the power settings of each power supply, the molten material as it flows through the non-circular opening of the bushing block can be selectively thermally conditioned.
