Answers
Answer:
the short answer is ‘yes’ but merely holding a match or lighter flame to Al foil obviously wont light the foil on fire like a sheet of paper. As Gamaliel pointed out, Al can be and is used to construct incendiary and explosive devices and in rocket fuels, e.g. . I have my doubts that there is actually an effective passivation layer on common foil that inhibits ignition. As Gamaliel pointed out exposed surface area is important but also a sufficient ignition temperature (activation energy) is necessary. The common claim that the dull side is due to atmospheric oxidation vs the shiny side being shiny because it’s been shielded is an “old wives tal
Answer:
It is not combustible because of it's structure, it's large surface area prevents it from combustion
