Abstract

Procedure and device for the homogenization and refining of the glass, characterized by the fact that after having directed the molten glassy mass to be treated at a temperature such that its viscosity does not exceed 1000 poises, this material is foamed in all its mass, this foaming occurs with a coefficient of expansion equal to or greater than 1.5 and preferably between 2 and 3, and that the viscosity of the material is maintained at values below 1000 poises until the foam sinks and recovery of the glass.
