If you heat wood enough (well over 200 centigrade) then the
finish applied won't matter much. Note that heating will affect
the structural integrity and strength.

He is joking, if you get your wood that hot, it burns.

Wood is routinely heated that much and more in industrial processes,
without any burning occurring. What will exactly happen at high
temperatures will depend on lots of circumstances.

As you know, all that is left unburned of a building after a big fire will
be the wood (big dimensions only).
