ABSTRACT:
A method for manufacturing glass wherein raw material is fed as a batch to a continuous glass-melting tank furnace, melted in a melting tank and passed to a refining tank via a submerged throat. The melt is heated in the refining tank to de-gas it, and then molten refined glass is delivered to a conditioning tank where it is brought to a desired working temperature. The refining tank is divided into upstream and downstream refining cells by a transverse sill. The melt in the upstream refining cell is heated to create a spring zone located towards the downstream end of that cell and a circulation of melt in that cell which feeds the spring zone.
