Abstract

The invention concerns a process and a device from the production of molten glass.According to the invention, measures will be taken to lead the current of the molten glass through the tank furnace so that cutoffs of the glass current between the surface of the glass bath, on the one hand, and the outlet opening on the other hand are avoided and a an equal holding period of all melt particles in the tank furnace is achieved.
