Abstract
In the formation of sheet material from molten glass, molten glass is formed in a melting furnace and transported through a precious metal delivery system to the forming apparatus. Disclosed herein is a method to eliminate carbon-containing contamination of individual components of the precious metal delivery system prior to their installation and use. The method comprises one or more heat treating steps in an oxygen-containing atmosphere prior to and/or during assembly of the component.
