What's the point? Aluminum also oxidizes immediately upon exposure to air, so it ends up in the same form on the surface of a pan as it is usually found in nature. I also would not rate iron as very toxic, it is part of the hemoglobin that is in red blood cells and necessary. If one has to much it is toxic, but then that is true of most elements, balance is the key. Marshall
