Holy hell: it’s been more than three months.
Back on June 9, I filled a clean, empty cartridge with an iron gall ink and fitted that into a clean Pilot Plumix fountain pen. The ink was Platinum Classic Cassis Black, one of Platinum’s new line of colorful iron gall inks for fountain pens. I put it nib upward in the pen cup at Fountain Pen Follies World Headquarters and Laboratory of Fancy Science. The experiment had begun.
I wanted to see how the iron gall ink would react over an extended period in contact with the Pilot’s stainless steel nib. Would the iron gall ink stain, corrode, gunk up or otherwise cause problems? Remember that we don’t worry about using iron gall fountain pen ink in pens with gold nibs, because gold does not react to the iron gall’s acidic element. But is there a problem with the more common, and cheaper, stainless steel nibs?
After a month, on July 11 or so, I thought it was time for an interim look at the Plumix. Click here for the full report, if you like, but the short answer was, all was well. The ink flowed, and the nib and pen were still perfect. I only used the pen once more, on July 22, briefly. Then I put the pen back in the pen cup and ignored it until earlier this week. Now it’s time for a three-month report.
