Abstract

See full text

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 electrical current.
