Abstract
The rate of melting glass batch to a liquid state is improved by providing sloped surfaces on the batch to enhance run-off of liquid. The slopes are provided by feeding batch as toroidally shaped aggregates.
Claims8
In a method for melting glass wherein particulate glass batch materials are fed into a heated enclosure, where the batch floats on the surface of a pool of molten glass therein until the batch becomes liquefied, the improvement comprising feeding the batch into the enclosure in the form of toroidally shaped aggregates whereby run-off of liquified batch from the unmelted mass of batch into the pool of molten glass is enhanced.
