He has restated that he sees no indications of modern pigments. Why isn't that the end of it then?

Because the few pigments that McCrone *did* identify (like the azurite of the blue paint), while consistent with the 1400 date, have been available all the time after that as well.

The instruments that McCrone used on the VMS can tell only the element composition and crystal structure of the pigments.  They did not give any actual date of manufacture or application. The only test that did so was the C14 test on the vellum, by someone else.

And also because there were several pigments that they could not identify (like he green paint), or which they provided absurd identifications for (like the "low-iron iron-gall ink" and palmierite).

All the best, --stolfi
