Oxidation is technically a fire, albeit very slow
2 comments

Fire is a type (fast) of oxidation. That doesn’t mean that oxidation is a type of fire.
really? citation?
"Fire is the rapid oxidation of a material" https://en.wikipedia.org/wiki/Fire
You might want to include the end of that sentence: "...in the exothermic chemical process of combustion, releasing heat, light, and various reaction products."

This confirms the, imo, common-sense position that no, oxidation is not just a slow fire. A fire is a specific type of oxidation process that involves the production of significant light and heat. In other words, it is only true that oxidation is a slow fire if one adopts a definition of fire that is significantly different from its ordinary usage.

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.
thank you
Fire is a phenomena whereby a fuel is combined with an oxidizer to make a new product in a manner that releases heat (ie: an exothermic redox reaction).

Rusting of metals fits that bill since heat is in fact released (just a super tiny amount and rather slowly), so it's _technically fire_ - although fire more commonly implies the rapid release of copious amounts of energy as part of the process.

thanks
