Palmierite (and atacamite?)

[Jorge_Stolfi]

the assumption of amateurish behaviour (as described), in this particular case.

I made no such assumption or statement.  The report itself says how the "palmierite" and "iron-free iron-gall ink" got into their conclusions: namely, as I described.  The output of the software (page 17, above the spectrum) was copied to the summary table, without any comments.

All the best, --stolfi
