[NewCandle] Nick's SEM photos of his aluminum corrosionexperiments

>Yes, I know.  So, where's the iron coming from?

There's a peak for iron in the control spectra, but it's not
reflected in the mass percentage analysis? The Al would
be corroded preferentially w/ respect to the Fe, leaving
an Fe enriched layer.

I have a related question about the control foil. Why is there
no oxygen in the analysis? We know there is an oxide layer
on the aluminum by virtue of it's having been exposed to air.
Yet no O is present in the analysis? Are the values
really good to .01%???
