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

Oven Temperature

Temperature in an oven is key to the curing process. However, temperature within an oven can vary, depending on airflow and the size of the batch to be cured. Regular ovens cure by heating the air. Infrared ovens, on the other hand, cure by emitting electromagnetic radiation that is absorbed by the parts. Since air does not absorb the light, energy is saved. Other advantages: the light can be used on localized areas and for special repairs. Also, distance from the light source can affect the cure.
