Zusammenfassung:	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 mitigate carbon contamination of individual components of the precious metal delivery system prior to and/or during their use. The method involves coating portions of the precious metal with an oxygen generating material prior to assembly of the component, and may comprise one or more heat treating steps of the component in an oxygen-containing atmosphere.
