According to Charles Pisano :
I attempted to use it the other evening and quickly became sick from the
fumes even though I had opened windows. After doing very little reading
(about small birds dying etc), I quickly realized super heating the
Teflon in an oven (or any teflon) to save oneself the trouble of
getting in there and cleaning it is not worth the potential harm to me
or guests.

_What_ "teflon in an oven"?

There is no teflon in ovens. What you may think is teflon is an enamel
coating which is designed for the temperatures of self-cleaning.

There's only teflon in an oven if you leave a non-stick pan in it.

Which you aren't supposed to do if you read the instructions.
