A method is disclosed of melting thermoplastic material, such as glass, in a refractory vessel (24), while protecting the refractory walls (26, 28) against corrosion and protecting the material from contamination by such corrosion. This is achieved by providing at least the sidewalls (26) of the refractory vessel (24) with an oxidizable metal liner (30, 30B), for example of molybdenum, the liner (30, 30B) being spaced away from but in close proximity to the sidewalls (26) to form an annular space (32). |
