Examining Noodler’s Ink Part 1

The one ink brand everyone is always talking about is Noodler’s Inks. People either love it or hate it. There doesn’t seem to be a lot of middle ground. As such, we want to add our two cents to this conversation, and we surprised ourselves with our tests and findings.

Controversy seems to follow in Noodler’s wake, and, yet, it doesn’t seem to disrupt people’s passion for the ink. From the stains-everything-it-comes-into-contact-with Baystate Blue to clever (and occasionally offensive to some) ink names and label designs, Noodler’s is always a top-selling ink.

I first got hooked on their ink with “Antietam” ink. As an armchair Civil War historian, I knew Antietam was this single bloodiest day of fighting in all of America’s wars. There were nearly 23,000 casualties at that battle. I got a macabre kick out of the Antietam ink looking like fresh blood when wet and dried blood when dry. It remains my red ink of choice. The ink has never clogged my pens or created any problems.

However, my favorite of their ink names is “54th Massachusetts.” As a regiment, it is the most famous African-American regiment of the Civil War. If you’ve seen the movie “Glory,” with Morgan Freeman, Denzel Washington and Matthew Broderick, it is that regiment. The American uniforms in the Civil War were blue. The men of this regiment were black. The ink color is blue-black. A clever ink pun. Unfortunately, as beautiful as the ink is, it clogs the hell out of my pens.

As a matter of fact, virtually every other Noodler’s Ink I have ever written with clogs my pens. As such, the only ink I use is Antietam, and I don’t recommend any other Noodler’s to anyone, unless they are only writing or drawing with dip pens.

Here are 11 swatches of Noodler’s Ink. The samples on the left were the control samples. The inks on the right were in the sun for 9 months.

Nevertheless, when I bought a large collection of ink several years ago, it came with a large selection of Noodler’s. As such, Dawn and I thought we’d put it to the test. Today’s selection remained in my sunniest window for 9 months. We also pH tested the ink to see how potentially corrosive it might be. As a quick refresher the scale between acid and base runs from 0 through 14, with 7 being neutral, such as pure distilled water. As always, we calibrated our testing equipment before testing the inks.

We were absolutely stunned by how light-fast these colors were. At worst, they lost a little of their luster and vibrancy after 9 months of sunlight. Most didn’t lose anything! Very impressive.

Noodler’s Ink also claims its is pH Neutral. We did not find that to be the case in these 11 inks sampled. However, they were much better regarding pH neutrality than many other brands. The important thing to keep in mind is that just because an ink is pH neutral doesn’t mean it doesn’t have ingredients that will still corrode your rubber ink sacs, diaphragms and seals. We did not test these inks in rubber ink sacs. The pH results below are simply raw data points.

Noodler’s Ink Name     pH

41 Brown                     8.4
Kiowa Brown              8.5
Golden Brown            8.1
Cayenne                      7.8
Apache Sunset           7.5
Polar Green ’09          8.7
Dark Matter                8.6
Nightshade                 8.4
Purple Heart               8.5
Gruene Cactus           8.3
Zhivago                        8.7

In conclusion, these 11 Noodler’s Ink were amazing for their color-fast testing. The pH is a little on the base or alkali side but no where near as far off the mark as many other ink brands.

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 21ºC.

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:

Ink Color              pH Measurement
True Teal                        7.1
Empyrean                      6.8
Blue Bahama                 6.6
Skies of Blue                 7.3
Cobalt Blue                   8.0
Regal                             7.2
Amethyst                      8.4
Raven Black                 8.3
Claret                            8.7
Pomegranate               8.3
Shiraz                           8.7
Cardinal Red               6.8
Blazing Sunset            6.7
Cocoa                           7.3
Forest                           7.1
Gemstone Green        7.2
Greystoke                    7.4

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