- Teflon will start to char at about 350 C (650 F). The rate of
- burning is also important. Slow charring, as occurs in org. chem.
- practicals and dry sterilization, allows complete combustion to
- carbonyl fluoride, which is less toxic. Rapid burning will lead
- to the formation of the serious nasties, this could be started
- by a magnesium flare but probably not in normal cooking.
