ABSTRACT:
An apparatus for heating glass-forming materials within a delivery conduit extending from an electric glass melting furnace to a connector channel is disclosed. The conduit is made from an electrically conductive refractory metal such as molybdenum and is used to conduct current from inside the furnace to its exit end in the channel. Joule effect heating between the exit end of the conduit and an electrode in the connector channel indirectly causes the glass materials within the conduit to partially melt, to the extent that the materials within the conduit may be exhausted from the conduit. A flange assembly for use with a molybdenum conduit is also disclosed.
