A fire releases the "heat, light and various reaction products" that it does because of the speed of oxidation. It's obvious even from the snippet I posted that slow oxidation is not actually a fire.

Yes, but aluminum oxidizes rapidly yet this oxidation process does not produce significant heat and light. So in this context, the independent heat/light requirement makes a difference!

Mill aluminium under inert gas into a powder and then release the pure unoxidized powder into the air.

My money is on some fireworks occurring.

Oxidation of aluminum does produce heat and light (the reaction is exothermic). It’s just a very small and fast fire.

It does as a powder.
