In a method of making glass or the like, wherein the batch materials are liquefied in a distinct zone from the refiner, the liquefied material is heated in an intermediate stage before being fed to the refiner. The heating entails intensified flames that impinge the surface to provide homogenization and a barrier to surface flow of low density material.

A method of making glass comprising: liquefying glass batch materials and tranferring the liquefied material to an entrance end of an elongated channel; heating the material in the channel to raise the temperature of the material; passing the heated material from a discharge end of the channel to a refining vessel; and impinging a transversely extending curtain of flames onto the surface of the material in the channel at a region between the entrance end and the discharge end with sufficient force to deform the surface of the material and to induce circulation of the material and to raise the temperature of the material.
