Heating and agitating method for multi-stage melting and refining of glass |
摘要 |
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.
