Title: Method of improving glass melting by ablation enhancement.
IPC: C03B3/00
Filed: 1981-06-01
Abstract: The rate at which glass batch is melted to a liquid state is improved by providing a series of depressions (34) having sloped surfaces in the glass batch at the charging end (17) of the furnace (20).
