A post on this discussion suggests this.
I only know (a little bit) about using electrolysis to do this, though on looking I see some chemical reactions can do it also. No mention of heat.

Hi Walt,
I don't have any direct experience with magnesium fires. Google tells me that magnesium vapor produced in a magnesium fire (very hot!) reacts strongly with oxygen, hydrogen, and even nitrogen, so the combustion products of mg + h2o will not include water. Said another way, mg is more reactive in a fire than hydrogen and oxygen!
Best,
Dan
