Iron Gall Ink Resources

My thanks to Ibby Lanfear for these up-to-date articles on iron gall ink.

This is some of the easiest-to-find, top-in-Google content; however, it often does not reflect up-to-date research. Even if it is easier to understand, consume with caution. These are linked here so that you can cross-check any pages you might have previously read. (The irony of signal-boosting out-of-date content, thus making it appear higher in the search results, is not lost on me.)
