Abstract
A current conducting melting vessel within which glass can be melted is provided. At least two induction heating coils are provided at selected locations proximate to the melting vessel. Power is selectively supplied to the coils to thereby selectively energize the coils so that the mutual induction of current in a non-energized heating coil adjacent to an energized heating coil is prevented via a switching element in power supply circuitry associated with the non-energized coil.
