True: wood doesn't burn in a fire.

Don’t get me wrong, wood is consumed in a fire, but wood itself doesn’t directly burn.

A chemical reaction from the wood emits gases – and the gases burn.  Anything that “burns” isn’t actually on fire.  It’s the gases from that object that burn, fueling the fire.  Fire is a side effect of matter changing forms.  Although I wouldn’t try to explain that to the piece of wood, as he is violently “changing forms”.
