ABSTRACT:
An apparatus and method for determining the elevation of the fusion interface between batch and molten glass in an electric glass-melting furnace is disclosed. A probe is driven vertically downwardly through the batch by a combination of a motorized drive assembly and a pneumatic hammer device. When the bottom tip of the probe penetrates the fusion interface, a current path is established from a furnace electrode through the molten glass to the probe tip, with such current flow thereby giving indication that the probe tip has descended to the elevation of the fusion interface.
