My aluminum CDs oxidize black, my aluminum sailboat rigging used to,
(before I got rid of it), aluminum cans that I tried to melt at one point
also turned into the a black form of the Aluminum oxide powder. Perhaps
there are other impurities in it that change its color, I don't know, I
just observe. Now is someone had a classic HP spectrometer I suppose I
could put this stuff in there and see what it said it was. :-)
