One handle is broken on our large saucepan, so I made a rather crude
wooden handle and glued it to the lugs. Only then did my son tell me
that this is the saucepan that goes in the oven, for stews.

I stuck it in the oven at 150C for a few hours, and quite a bit of resin
has oozed out of the wood, but the wood isn't burning.

I've just turned it up to 180C, and I'll keep an eye on it.

Any idea how hot it can go before it chars or bursts into flames? I'm
told that sometimes stews go up to 200C.

Table 1 on this pdf suggests 200C is getting pretty close to ignition

Ignition temperature for cellulose based reading matter, according to
Ray Bradbury and my 8 digit calculator, corresponds to a temperature of
232.77777 deg C. :-)

I am afraid Ray Bradbury's title annoyed me in the same way so much of
his work did. I dislike science fiction by people who obviously have no
grasp of science or engineering. The title is a gross example of
spurious precision, If the proposition that paper ignites in air at
about 450degF is true at all, then it would be reasonable to expect in
practice that it happened for a given book somewhere between +/- say
50degF of this figure.
