<VV> Glass LOF

[N. Joseph Potts]

I'm trying to figure out how you make a curved piece of glass by floating it
on some liquid.

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.
