Sorry, Q, I should have specified, since we're now talking about more than one product on the thread. The Remoska is the cooker that is Teflon coated. Their site calls it "TeflonO".

According to Wikipedia, polytetrafluoroethylene (Teflon's chemical name) "begins to deteriorate after the temperature of cookware reaches about 500°F (260°C), and decompose above 660°F (350°C).[12] These degradation products can be lethal to birds, and can cause flu-like symptoms in humans. By comparison, cooking fats, oils, and butter will begin to scorch and smoke at about 392°F (200°C), and meat is usually fried between 400–450°F (200–230°C), but empty cookware can exceed this temperature if left unattended on a hot burner. A 1959 study, (conducted before the U.S. Food and Drug Administration approved the material for use in food processing equipment) showed that the toxicity of fumes given off by the coated pan on dry heating was less than that of fumes given off by ordinary cooking oils."

The hot-burner issue is irrelevant here, of course. Anybody know how hot the Remoska gets when cooking? Much has been said here about how hot the lid gets; is that coated with Teflon as well?
