A method of making a glass sheet includes exposing a refractory block material comprising at least one multivalent component to a reducing atmosphere for a time and at a temperature sufficient to substantially reduce the at least one multivalent component of the refractory block material. The method also includes flowing molten glass over the refractory block material that has been exposed to the reducing atmosphere while preventing substantial re-oxidation of the at least one multivalent component.

Method of making glass sheets with gas pretreatment of refractory

A method of making a glass sheet includes treating a refractory block material comprising at least one multivalent component with a vehicle comprising at least one redox altering component or precursor. The method also includes flowing molten glass over the refractory block material, wherein the treatment of the refractory block material with the vehicle comprising at least one redox altering component or precursor reduces the amount of oxygen production resulting from interaction between the at least one multivalent component and the molten glass.
