As a side note, concerning
the oxidation of aluminium, consider that the silver powder in fireworks
is powdered aluminium! Have a friend , whose dad told of his experience
with it (powdered)-- was used to make aluminium based paint- he was told
by his boss to get rid of it-- threw it into an incinerator-- and,
KABKOOIE ! as info, Jim NN7K


IIRC, 'Thermite' is made from Iron Oxide and Aluminium powder, and that
burns rather hot!
