Abstract of the Disclosure The rate at which glass batch is melted to a liquid state is improved by providing a series of depressions having sloped surfaces in the glass batch as the charging end of the furnace. The sloped surfaces of the depression permit run-off of melted glass batch, thereby exposing the surface of fresh glass batch to the heat of the furnace. Depressions in the glass batch are made by projecting periodically a plurality of hori- zontally spaced independently suspended and independently operable tapered pothole-producing members into the glass batch material and pushing the glass batch beneath the tapered member into the below the surface of the molten glass a distance about equal to the height of the glass batch blanket. The action of the tapered member in producing the depression also provides a wave action to the body of molten glass in the vicinity of the charging end of the furnace, which enhances the rate of melting of glass batch materials. Better coverage of the glass batch on the surface of the molten glass is also observed.
