A glass manufacturing process comprising the steps of: forming liquid-containing glass batch agglomerates; charging the agglomerates to a predrying fluidized bed, withdrawing the agglomerates from the fluidized bed and charging them to a preheat hopper; withdrawing the agglomerates from the preheat hopper and feeding them to a glass melting furnace; withdrawing flue gases from the glass melting furnace and passing them through the preheat hopper to heat the agglomerates therein; and withdrawing the flue gases which have passed through the preheat hopper and passing them through the fluidized bed to predry the agglomerates therein. An apparatus for producing molten glass comprising: means for forming glass batch into agglomerates; a fluidized bed predryer; means for supplying the agglomerates to the fluidized bed predryer; a vertical bed preheat hopper; means for supplying the agglomerates from the predryer to the preheat hopper; a glass melting furnace; means for supplying the agglomerates from the preheat hopper to the glass melting furnace; means for supplying flue gases from the glass melting furnace to the preheat hopper; and means for supplying flue gases from the preheat hopper to the predryer.
