Levenger’s Ink Kicks Ass!

Mathematical and computer genius Alan Turing famously said, “Sometimes it is the people who no one imagines anything of who do the things no one can imagine.” In addition to being one of my all-time favorite quotes about people, it seems to apply to the world of fountain pen inks, too.

Here is a side-by-side comparison of Levenger’s ink left in the sun for 3 months and the proof sample saved in the dark.

Ink collectors today understandably go ga-ga for Iroshizuku, Diamine, ColorVerse, J. Herbin, Noodlers and many other brands. Yet, often overlooked, is Levenger’s Ink. In many respects, Levenger’s kicked off the ink-color craze a decade or two before our current manufacturers and spectrum were readily available. Levenger’s has had scores of inks of every hue available since some time in the 1990s. Better yet, they are far more affordable than the competition.

Nevertheless, I kinda blew them off…until I stumbled into a large collection for sale. When Dawn and I started testing them for UV light fastness and pH balance, we were blown away.

We started testing 17 colors in March. From March 7, 2021, through June 7, 2021, we hung these samples in the sunniest window of our house. Afterward, we tested the ink still in the bottles with a pH meter calibrated to 21¬ļC.

Here is a side-by-side image of Levenger’s inks left in the sun for 3 months and the sample proof left in the dark.

Without a doubt, these are the most consistently light-fast inks we have tested to date. Even the worst-hit inks were still very close to their original colors. Blue Bahama likely lost the most vibrancy, but it is still easily read and distinguished. Cardinal Red faded to a rich pink, but it is still quite legible. Raven Black, Gemstone Green and Greystoke got DARKER in the sun!

Given the great results from the light-fast testing, we feared the worst with the pH tests. BUT! We were only further dazzled. Many of the inks were very close to neutral, and none of the inks veered off the spectrum of acidic or alkali.

As a basic chemistry refresher, 7 in a pH test is neutral. Distilled water is 7. The closer to 0 you go, the more acidic something is. In the opposite direction going up to 14 is more base or alkali. In theory, you don’t want an acid or a base sitting in your ink sac for too long. Yet, one thing we always like to remind people is that regardless of what the pH result is, we do not know the chemistry of the ink nor how it interacts with your rubber ink sacs, celluloids or converters and the like. Depending on the chemical reaction between the ink and what it is resting in, a neutral ink can do damage and an acidic ink might be safe. The pH measurement is simply a data point we find fascinating, but it doesn’t necessarily indicate which inks are safest for your pens. With that in mind, here are our Levenger pH results:

As always, I hope you find this information to be interesting and enjoyable.
