<p>An electric glass-melting furnace is disclosed having a glass heating apparatus comprising, in a first embodiment, a chamber adapted for holding a body of molten glass, arc electrodes positioned above the body of molten glass; and first and second electrodes positioned in the body of molten glass. Equal current flows through the first and second electrodes. A second embodiment of the invention uses only resistive heating produced by equalized current flow through individual electrodes. A third embodiment of the invention uses a combination of resistance heating electrodes and an arc electrode in which the current flow is equalized through individual electrodes.</p> |
