250 degrees Celsius = 482 degrees F.

Stovetop: This is way above even cooking oil preparations (which would heat the whole pot), and much, much higher than ANY local (pot bottom) temperatures for normal cooking. Hence = It's NOT a realistic temperature any any cases other than the pot burning up.

Oven temperatures: Most cooking is between 400 and 450, it's possible 480 degrees can be reached. But, baking is lower temp, and Teflon cookware (handles, rivets, the Teflon itself) isn't used this way. AS most have pointed out in this thread, 482 degrees in a (dry, or empty) pot or pan is done by steel or ironware.

The PREMIS that widespread distribution of the waste chemical from Teflon (chemically-lined) stove top cookware is foolish: There are too few pots produced this way, of those pots and pans, too few burn up this way, and of those few that do burn inside a house, the worldwde spread of chemicals from those pots isn't the source of the chemicals.

Agreed. My "pop-up timer" shot out of the bird when I saw 250^oC.
