Shelf Life of Fountain Pen Ink2013/01/28
A thread at Fountain Pen Network about moldy ink made me curious about which brands of ink still contain phenol or another effective biocide. The EU’s rules for the manufacture of inks has affected a few brands though new formulations seem to have improved recent batches. While I have had a few bottles go bad, never has that happened with Noodler’s, Diamine, or any Japanese ink in my collection. Nor has it happened with ink in my collection manufactured more than five years ago.
There is no intent to bash any ink but rather to find ink that, if stored for an extended length of time, is most likely to remain untainted. Parker Penman ink is a good example. It was only manufactured from 1993-2000 which predates any government tinkering. My stash remains viable with the exception of one bottle of Ruby that arrived partially used and containing SITB. The former owner was the culprit in that case.
So who is making the good stuff these days?
This bottle of Noodler’s Ink was purchased more than seven years ago and remains untainted. That’s what I call “the good stuff” and ink that is worthy of high praise.
