Glass

Float glass is a sheet of glass made by floating molten glass on a bed of molten metal, typically tin. This method gives the sheet uniform thickness and very flat surfaces. The float glass is cooled in a controlled protective atmosphere of roughly 5-10% hydrogen in nitrogen.  Nitrogen is used to blanket, and prevent from oxidising, the tin bath.  Hydrogen reacts with oxygen that diffuses into the float bath atmosphere and keeps the tin from reacting with oxygen.
