    Abstract: A rectangular furnace has openings at one end through which the batch material to be melted is introduced, and throat openings at the opposite end through which the molten glass can flow to forehearth and feeder installations. The lengths of the sides of the rectangular furnace are related to these opposed ends in the range of ratios between 3:1 and 4.5:1. The sole source of heat is provided by burners in the withdrawal end, so arranged as to fire upstream toward the batch charging end, a stack being located at the latter end to allow the products of combustion to escape from the furnace. The furnace roof provides a space for these combustion gasses above the melted and melting glass which has a constant vertical cross-sectional size throughout its length.

    Abstract: A SQUARE SHAPED FURNACE HAS DUAL GALL BATCH CHARGERS AT ONE CORNER, AND A THROAT THROUGH WHICH THE MOLTEN GLASS CAN BE WITHDRAWN AT A DIAGONALLY OPPOSITE CORNER. THE FURNACE HAS ROOF WITH A MAXIMUM HEIGHT ALONG A LINE CONNECTING THHE DIAGONALLY OPPOSED CORNERS, AND THE HEIGHT DECREASES TOWARD THE OTHER TWO LATERALLY OPPOSED CORNERS OF THE SQUARE FURNACE. THE MOLTEN GLASS IS HEATED FROM ABOVE BY BURNERS, AND LATERALLY OPPOSED ELECTRODES MOUNTED IN BAYS IN THE FURNACE SIDE WALLS EXTEND INTO THE MOLTEN GLASS FOR JOULE-EFFECT HEATING.
