Abstract

A melt tank for the production of a glass melt having a low portion of bubbles. The melt tank includes an inlet opening, an outlet opening, a floor, at least two side walls that adjoin the floor, a roof. The glass melt having a first bath depth in a melting segment, a second bath depth in a refining segment, and a third bath depth over a threshold between and smaller than the first and second bath depths. An electrically produced first heat energy is supplied via a multiplicity of electrodes that extend into the glass melt and a second heat energy is produced by the combustion of fossil fuel via at least one burner. Also, a method for producing a glass melt.
