Doc,  Unless you are pulling our leg the LOF does stand for Libbey, Owens, 
Ford.  Probably most glass today is "float glass" made by floating the glass on 
another liquid--molten tin if memory serves me.  The process was invented in 
Britain about sixty years ago (I think).  The tempering process takes place 
after the glass is cut.

If anyone out there has some real world experience in glass manufacturing 
they can give the definitive answer.
