Apparatus and methods for manufacturing glass

Abstract

A glass manufacturing apparatus includes a melting vessel including an interior chamber containing molten glass. A first electrode, a second electrode, a third electrode, and a fourth electrode extend within the interior chamber. A first electrical power supply is electrically connected to the first electrode and the second electrode and delivers a first electrical current. A second electrical power supply is electrically connected to the second electrode and the third electrode and delivers a second electrical current. The second electrical current is out-of-phase with the first electrical current. A third electrical power supply is electrically connected to the third electrode and the fourth electrode and delivers a third electrical current. The third electrical current is out-of-phase with the second electrical current. Methods for manufacturing glass are provided.
