Aluminium foil to Aluminium Oxide?

Firstly, I want to know if the product from this is Al2O3 (Aluminium Oxide):
I took a piece of Aluminium foil and lightly crumbled it into a ball. I weighed the Al foil ball, it was 0.334g. I then torched the Al ball with propane until near destruction, the aluminium foil shrunk and changed colour to a more dull grey metallic surface. Once cooled, I weighed the now smaller and harder Al ball and the weight was 0.38g, an increase of 0.044g which I beleive is due to oxidation. Is the product aluminium oxide? Or a partial oxidation?
Secondly, what is a good 1step method to create aluminium oxide from aluminium foil with a high grade yield? I already know of the aluminium and NaOH to create aluminium hydroxide is then heat until it decomposes to aluminium oxide; < which I think is one step too many.
I appreciate any input. And thanks for reading.
