Re: The Vinland Map's Ink

I'm still waiting. Plenty of rhetoric and comments on other topics, but
no answer to my query...

" I would like those who regard the VM as an authentic medieval
document to answer my question ...If the map is really medieval, what
is a PLAUSIBLE explanation for the appearance AND composition of the
inks that is consistent with the age of the parchment?"

It is a really weak answer to argue(?) that we don't really know what
the exact composition of the ink is and therefore we cannot discuss
plausible scenarios. We DO know a number of things and these things
that we DO know have to be placed into a plausible scenario consistent
with a medieval origin.

OK. What do we know NOW that requires plausible explanation?

(1) there is anatase (TiO2) in the ink (but not on the parchment). This
anatase is free of associated clay minerals (XRD, SAED, TEM shows no
clays!) therefore ruling out a "natural" source (unless someone can
PLAUSIBLY explain how a natural trace component clay anatase could have
been completely separated from the clay which is 97% of the sediment)..

(2)The anatase in the ink is a dead-ringer for commercial anatase...not
available until circa 1920.
(3) the ink is NOT an iron-gall ink, which was the standard ink of the
period and which is found (free of titanium!) on the Tartar Relation
and the Speculum Historiale. The experts at the British Museum (e.g.
David Baynes-Cope) found that the VM was unlike any of the many
documents that they had seen.
(4) The ink (as observed today) is a two-component "ink". There is an
underlying yellow-brown material with commercial-grade anatase and an
overlying carbon-based material, much of which has flaked off.

Now, regardless of what the precise composition of the ink is, what
explanation can be offered that will explain all of these four things
and will also be consistent with authenticity?
And, please...no more name-calling, gutter langauage, ad hominem
criticisms, or diversions from this point. Thanks, KEN
