  1. Aluminum foil is NOT tin and does NOT contain any tin!

    The sharpening agent in aluminum foil may be attributed to the ultra thin later of aluminum oxide coating the foil which occurs when the foil is first exposed to air during manufacturing.

    Aluminum oxide (Al2O3), also known as corundum and forms some gem stones such as rubies and sapphires, is a very hard substance used in commercial metal cutting tools.

    Tin (Sn) is totally different metal.
