Abstract

A glass melting tank with at least one pair of heating electrodes projecting into the glass melt and a process for melting glass are described. The glass melting tank has, at least in the area of the melt, a narrowed cross section area and the glass melting tank has at least one heating electrode in front of and a corresponding heating electrode behind the narrowed cross section area and in this way an increase in the temperature of the melt can be achieved in the narrowed area. A preferred application is the refining of glass melts.
