Glass tempering isn't done with oil, it's done with air. Cool the surface 
quickly, and then the delayed cooling of the core compresses the skin, making it 
FAR harder to initiate a crack. But they aren't cooling those curved panes in 
a float process. They cast the glass initially on a pool of molten tin, and 
that pool has zones which allow it to cool on the molten metal surface, hence 
float glass. A great way to make VERY smooth glass without polishing.

Harry,

I may be wrong but I believe that it is both.  If memory serves me,  Libby 
trade marked the process with the name of Liquid Oil Float.  Of  course, this 
is 
just hearsay.
