APPARATUS AND METHOD FOR MITIGATING ELECTROCHEMICAL ATTACK OF PRECIOUS METAL COMPONENTS IN A GLASS MAKING PROCESS

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. 公开了用于形成玻璃制品的装置和方法，其中通过沿着第一电路径在相对的通电电极之间在熔融玻璃中建立电流来在耐火容器中加热熔融玻璃。所述熔化容器包括与所述熔融玻璃接触的贵金属部件，以及在所述贵金属部件附近的至少一个非通电电极。所述至少一个非通电电极和所述贵金属部件分别形成与所述第一电路径并联的第二电路径和第三电路径，使得所述第二电路径中的电流减少，由此减少所述贵金属部件中的电化学反应。
