OK, I need to gather more evidence. Will come back later.
Quote:"Hundreds of years ago large parts of the text would have already faded away..." - I'm not sure I agree. As far as I understand, the type of pigmentation that this iron-based ink produces is quite durable. I'm not an expert, but I've heard that there is an actual chemical reaction that alters ("burns") the very vellum, so it's not just some coloring on top of the page.
Yes, I know the chemistry of iron-gall ink. But the reasoning should go the other way: given the amount and kind of fading that we see on the VMS, it cannot be iron-gall ink.
Before someone mentions it: yes, I read the McCrone report, and, well, let's say I was not impressed. But please let me leave this discussion for later, too.
All the best, --jorge
