Flat glass is almost exclusively "Float Glass" now.
Developed in the 50's, glass is molten on the surface of a pool of lead, tin, or other fairly low melt point metal, and drawn off as an extrusion.

Is 2,000 F the temperature of the glass or is the temperature of the tin, because it seems awfully hot for tin.
I think 2,000 F is the temperature of the glass when it starts to flow over the tin and it when gets pulled off at the end it has dropped below 1,200F and solidified. Unfortunately I have no idea of what temperature the tin is held.
