I didn't know about the 35% O2 for burning, thats interesting.

Further heating to 800°F (426°C) in air may result in a heavy oxide layer because of increased diffusion of oxygen through the titanium lattice. Above 1200°F (649°C), titanium lacks oxidation resistance and will become brittle.


This is what I was referring to above. I'm guessing that a unfilled pot on a pocket rocket could very easily get up to 426C and could get to 650C+ (a propane torch can reach 2000C). Of course the oxidation numbers are not a switch and time exposure has a lot to do with this. But you can do some damage to your pot.

All of this just goes to show, whatever the material (unless its ceramic coated Ni-based superalloy, which would be one heavy, expensive pot, but might make a decent jet turbine blade) don't leave an empty pot on a burner turned on high.
