Abstract
A method is set forth for controlling the height of batch material on the surface of a molten bath in a cold-crown or vertical melting furnace by measuring the level of the upper surface of the batch material, the level of the fusion line between the batch and bath, and the effective hydrostatic head of the molten glass and batch material thereon over a predetermined height at such known fusion line level. The thickness of the batch blanket is then determined from the level of the fusion line and the measured level of the top of the batch blanket, and power input and rate of batch distribution are controlled to maintain such desired levels and accordingly a predetermined batch thickness, by continuously monitoring the level of the batch material and the effective hydrostatic head.
