New video: "Is the Voynich Manuscript fake?"

Wrt, Titanium in inks , i searched about and couldnt find anything but this caught my eye.

regarding medieval type inks ;

" a plausible medieval contaminant,  the iron−titanium mineral ilmenite (FeTiO3)"

This more recent article (2012) says that "ilmenite in medieval inks is a realistic possibility" though no comparative study of medieval inks, looking for titanium compounds, has been done:

The presence of titanium in other medieval inks suggests that the presence of ilmenite in medieval inks is a realistic possibility. Further investigations of medieval inks to determine the nature of a titanium containing compound or compounds is required in order to correctly resolve this matter [16].

In the controversy about the Vinland map's authenticity, it was argued that the presence of anatase may not be evidence of forgery:

"The source of the iron in medieval inks is green vitriol, an iron sulfate," Olin continues. "Green vitriol would include anatase if the iron source from which it was made included the iron-titanium mineral ilmenite."

However "synthetic anatase in a distinctive crystalline form" (as found in the Vinland map) should not be found in medieval inks:

The McCrones found the ink on the map to contain synthetic anatase in a distinctive crystalline form and colored with a yellow impurity. Synthetic anatase in this form first became available around 1920. Since that time, various institutions, organizations, and individuals, each with their own agenda, have sought and failed to challenge the McCrones' findings.
