Abstract

See full text

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.
