Meet the Ink Test Guru

Several years ago I met Donn D. at the Chicago Pen Show. We got to talking outside of the main room afterhours, and he was the one who introduced me to Ink-Fast Tests. He had a binder of very organized ink swatches that showed what an ink looked like when protected from the light, what it looked like after it had been left in the sun for 3 months and after it had been left in the sun for 6 months.

As I was on a quest for the perfect replacement blue for my beloved Waterman Florida Blue, I began making ink tests for this site. I figured you would be as curious as I am about how ink holds up to UV light.

Donn and I got together at this year’s Washington DC Pen Show and resumed our inky discussions. I asked if he would be so kind as to share some of his tests on the blog, and he said, “Yes.”

Included in this post are 4 pages of his tests of Pilot ink, Diamine ink, Noodler’s ink, Waterman ink, Parker ink and Pelikan ink…among others.

Donn described his methodology as such: “I exposed fountain pen ink samples to ultraviolet light from the sun for 3 months and 6 months.  The exposure method involved simply taping them to the inside of a patio door, which does not block UV very well.  I exposed all samples in the same manner, but not at the same time, and have no record of the number of cloudy vs. sunny days for each test.  The paper was standard office copy bond.

The inks in this test happen to be colors I like, rather than a general test of a manufacturer’s entire product line.

What surprised me most was how well green inks held up, and a chemist friend speculates a copper compound may be involved.

Note: Test sheet #1 shows 6-month results only.”

Thank you, Donn, for sharing so many of these ink tests. Everybody else, I hope these help you in your quest for the perfect inks.

Click on any of the images to see a larger, clearer representation of the inks tested. Please also note that these are not performance tests of the ink inside a fountain pen. Some of these inks are not as well suited to vintage pens as others. This is strictly to showcase how an ink will hold up to time and light. (For example, Noodler’s Ink often clogs the hell out of vintage pens. Beautiful inks but a pain to deal with unless you love spending hours cleaning pens.)

Ink Fast Test #5: Diamine & ColorVerse

I went a little ink crazy at Vanness Pens during the Little Rock Pen Show, back in April. Afterall, they only have the world’s largest selection of ink…and they were kind enough to ply just about all of the vendors and weekend pass holders with free food (including chocolate-covered bacon) and beer. As such, I dove further down the Diamine rabbit hole…and then I won a free bottle of ColorVerse Kepler’s Laws ink in a raffle!

These are before and after samples of Diamine and ColorVerse inks left in the sun for 3 months.

Now it is time to share my experiences with the inks. My all-time favorite blue ink is the old Waterman’s Florida Blue, so I had to try some of Diamine’s Florida Blue. Diamine Florida Blue is a very pale blue that is just a little too deep to be turquoise. I still prefer the much darker Waterman version. I put a test sample in a sunny window, and the UV rays completely erased the Diamine Florida Blue test sample! Definitely not archival quality ink, although it is attractive for artistic writing uses.

Diamine Mediterranean Blue ink is gorgeous when used in a really wet pen. The photo proof sample isn’t as generous of its deeper hues of blue. It could be my replacement for Waterman’s discontinued ink…except it too was completely erased by the sun!

My favorite ink find of the past year or two was Diamine’s Ancient Copper. When I saw the Diamine Autumn Oak at the shop, it looks about a shade lighter in a rich orangy brown. It is a beautiful ink when fresh. Annnnd, luckily it holds up a little better than Diamine blues in 3 months of sunlight.

Of the four inks, ColorVerse’s Kepler’s Laws held up best to the sun. It is a rich red color with purple hues and a little shimmer when fresh. (I don’t see the shimmer, but all of my pen pals insist that they see it.) It writes better than I thought it would. I was really worried it would clog up my pen, but I didn’t have that experience in a Delta Fusion A2 I have with a stub nib. After 3 months in the sun, the more vibrant red aspects vanished, but a slightly watery merlot color remained strong.

And for those who are curious about the black header ink, it is the already tested and proven Aurora black. A bad-ass ink that never quits.
