<p>A glass melting furnace (50, 150, 250, 350) is disclosed having a refractory melting vessel (60, 160, 260, 360, 460, 560) provided with a protective liner (70, 170, 270, 370, 470, 570) formed of an oxidizable refractory metal such as molybdenum. The liner projects upwardly within a molten bath (80, 180) contained within the vessel and through its fusion line (78, 178, 278, 378, 478, 578) into a batch blanket (82, 182) retained thereabove which is low in carbonates. The upper end (71, 171, 271, 371) of the liner is provided with a seal to pre- ventthe 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.</p> |
