ABSTRACT:
A glass melting furnace is disclosed having a refractory melting vessel provided with a protective liner formed of an oxidizable refractory metal such as molybdenum, wherein the liner projects upwardly within a molten bath contained within the vessel and through its fusion line into a batch blanket retained thereabove which is low in carbonates. The upper end of the liner is provided with a seal to prevent the flow of batch material between the liner and the refractory vessel and thereby prevent contamination of material behind the liner and reduce corrosion of the refractory vessel.
