How do they keep the Teflon coating on pans?

ahh I had this in a pub quiz once... Did you know that Teflon, the non-stick coating used on pots and pans, holds the title in the Guiness Book of World Records as being the slipperiest substance on earth. It was invented by Dr. Roy J. Plunkett http://www.chemheritage.org/classroom/chemach/plastics/plunkett.html Scientifically speaking, Teflon will not chemically bond to anything, but can be forced mechanically into small nooks and crannies. This slippery substance adheres to their surfaces once manufacturers sandblast them to roughen them, apply a primer, and embed the Teflon into the primer. If they get scratched you may find that the coating does wear off over time.

All I can say is thank heavens for Teflon. I'm not a cook and I hate cooking but the only thing I love to make is an omelette, and not having the right pan for an omelette is a disaster waiting to happen, so mum bought me my own teflon coated pan, and it's a dream, it's a miracle all my omelettes come out WHOLE and not a pile of gunk. Whoever invented teflon should get a knighthood, one of the best inventions that has saved the day in the kitchen. It's marvelous and the inventor must be laughing all the way to the bank.
