Assuming that the McCrone and Brown/Clark analyses did not
mysteriously select freakishly anomalous sampling locations, I'd
have to ask why, despite the wide variety of analytical techniques
used, there have been no reports of the significant quantities of
tannic acid you would expect to find in the Vinland Map ink if Jim
Enterline's theory is correct.
The answer may simply be that nobody has done a determinative test
for tannic acid. Ever since the McCrones announced that the binder
looked like early titanium paint, everyone has assumed that it
is. The elemental ratios in the analysis are certainly not
inconsistent with tannic acid.
The problem for Jacqueline Olin's theory is the genuinely freakish
ratio of titanium to iron (resulting from both a surplus of titanium
and a shortage of iron, relative to known iron gall inks) in the
Vinland Map ink in situ.
The relative shortage of iron is obviously explained by the
Enterlline scenario. And the surplus of titanium is explainable by
my (or other) transfer scenarios

The last I heard, the ink is fading on the map, thus settling the
point. Am I wrong? Has anyone seen it lately?
Yes, it is fading, and I was one of the first to comment on that. I
suggested that it is the result of remnants of the hypothetical
bleaching involved in my transfer scenario. The ink does have
elevated chlorine. See the Appendix in my book, _Erikson, Eskimos & Columbus_.
