Abstract
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.
