If it will oxidize, it will burn. That is, if the compound will
give up an electron and recombine to form a different molecule - it
will "burn". You can do this with regular steel bar stock and enough
pure oxygen. But if you divide it fine enough (grind it) the 'dust'
will combine with atmospheric o2.

Oh, it's easier than that.
Just apply a flame to a bit of steel wool.
Or gold leaf.
