Abstract: Apparatus and methods are disclosed for forming a glass article in which molten glass is heated in a refractory vessel by establishing an electrical current in the molten glass between opposing powered electrodes along a first electrical path. The melting vessel includes a precious metal component in contact with the molten glass, and at least one non-powered electrode proximate the precious metal component. The at least one non-powered electrode and the precious metal component form second and third electrical paths, respectively, in parallel with the first electrical path such that an electrical current in the second electrical path is decreased, thereby reducing an electrochemical reaction in the precious metal component.

Abstract: Apparatus and methods are disclosed for forming a glass article in which molten glass is heated in a refractory vessel defining a space interior to the refractory vessel. A precious metal component is exposed to the interior space. The apparatus includes first and second electrodes exposed to the interior space. A first electrical power source configured to supply a first electrical current is connected between the first and second electrodes. A second electrical power source is connected between the precious metal component and at least one of the first electrode or a first auxiliary electrode and configured to provide a second electrical current out-of-phase with the first electrical current. A third electrical power source is connected between the precious metal component and at least one of the second electrode or a second auxiliary electrode and configured to provide a third electrical current out-of-phase with the first
