A method includes electrolyzing water into hydrogen, combining the hydrogen with nitrogen to generate forming gas, delivering the forming gas to a reducing environment zone, and processing an intermediate material into a product material in the reducing environment zone. The step of processing the intermediate material into the product material may include processing a glass melt into a float glass ribbon on a tin melt and then cooling the float glass ribbon into sheet glass.

A novel apparatus and method for producing flat glass by floating molten glass on liquid tin, significantly improving the efficiency of heating the tin and reducing or eliminating the need to anneal by eliminating the stress introduced by pulling the glass across the tin bath. The apparatus directly heats and melts the tin by exposure to high-intensity infrared energy through surfaces of the tin-containing tub, said tub made from a material that is transmissive at selected infrared wavelengths.
