Abstract

In a process for liquefying glass batch and the like, wherein a layer of batch is maintained as a lining in the liquefaction vessel, the thickness of the lining is monitored by measuring the temperature in a region facing an end portion of the lining. Preferably, a series of thermocouples serves to determine the location of the face of the lining on which liquefaction is taking place.
