Three Months and Counting: An Extended Test of Platinum Classic Line Iron Gall Inks with a Stainless Steel Nib Fountain Pen

Pilot Plumix

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.

Ink Dips: Rohrer & Klingner Verdura

Rohrer & Klingner Verdura

Ink Dips is a more casual, and potentially moronic, ink evaluation than is normal here at Fountain Pen Follies. Instead of carefully evaluating an ink I’m interested in, the point of Ink Dips is to blindly pick an ink sample from a box of the neglected or nugatory. Then I fill that sample into one pen and see what I think. It’s an exercise that’s a bit dippy.

Rohrer & Klingner Verdura. There’s nothing wrong with Rohrer & Klingner Verdura, but I can’t say that it’s an especially interesting shade of green, either. I found this ink absolutely fine, even cheerful, but probably not the green for me.

Pen of the Day: Parker Duofold Centennial

Parker Duofold Centennial Black and Pearl with Rohrer & Klingner Fernambuk ink

Parker Duofold Centennial with medium stub. This is the modern Duofold in Black and Pearl. I saw a few of these at the pen show. Along with a number of vintage Duofolds in the original black and pearl celluloid. So it’s nice to take out mine again.

However, the main thing I’m interested in today is the ink, Rohrer & Klingner Fernambuk.

More Inks for Lamy’s Charged Green Al-Star


Here are a few more ink possibilities for the new Lamy Charged Green Al-Star, these suggested by readers of the original post, here.

The first is Pilot Iroshizuku Chiku-rin, as suggested by Rafael.  I think Chiku-rin really works with the suggestion of celery green in the pen.  It might be slightly greener, and the pen slightly more yellow, but I like more green, and I like this combination.


Second is Derek’s suggestion of Rohrer & Klingner Alt-Goldgrün. This is a very popular ink with nice shading, that I think of as an avocado green.  And I think this color really works beautifully with our Charged Green Al-Star, too.


Chiku-rin and Alt-Goldgrün are both yellow-greens.  With the Charged Green Al-Star, that’s clearly the way to go — or else greenish yellow inks.  Thanks to Rafael and Derek.
