Where did it all begin?

Nonstick coatings hit the selling floors in the early 1960s.

The first nonsticks were made primarily of polytetrafluoroethylene (PTFE). PTFE has the lowest coefficient of friction (CoF) of any known solid. In other words, the majority of materials (in this case foodstuffs) do not stick to it.

PTFE's low CoF "releases" the materials, making it easy to separate them from the coating. Therefore, on nonstick pans, most substances are easily removed from the surface.

Unfortunately, PTFE is also very soft and, if unprotected, wears quickly. While early nonsticks had good release, they were soft and wore out after little use. The result: nonstick-coated cookware earned the reputation of being "disposable".

The Curing Process

Cure Time

There tends to be an inverse proportion between cure time and temperature. With some materials (such as castings), high cure temperatures can cause blistering (outgassing) of the metal. So lower temperatures are used - for longer periods. However, lowering the cure temperature can occasionally reduce the characteristics sought, no matter how long a coating is cured. And too long a cure can degrade a coating (including its color).
