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 may be provided by feeding batch as shaped aggregates, contouring the surface of a batch layer, or by creating openings through a batch layer. The batch may be compressed or compacted into aggregates before they are deposited as a single layer onto a pool of molten glass contained within a glass melting furnace.
