Archival Qualities Of Iron Gall Inks

Thanks for the reply. I was checking out your test results. Very interesting and thanks for doing that. Have you ever tested the de atramentis document inks? I have wanted to get some as I really like the idea of being able to mix colors but I can’t find anywhere in Canada to get them. I may order from the USA but I am trying to avoid unknown duties etc.

I haven't tested document inks yet, though I've always been curious. They are said to be very permanent.
