A Potpourri of Ink Tests

As we have been conducting our ink tests, we ran into a grouping of mostly orphaned bottles that wouldn’t make for a very big story individually. So we tested them together and got them all on one page.

The ink proof sheet is on the left and the UV tested inks are on the right. Click the image above to get a better look at the ink tests.

This batch of inks was given a UV light fast test in our sunniest window from March 7, 2021, to June 7, 2021. We also tested the pH levels of the inks to see just how neutral they are. The following is all raw data that we thought you might find interesting. As we do not know the chemical composition of each ink or ink sac/converter it might go into, a pH neutral ink does not guarantee it won’t have a bad chemical reaction inside your pen. We have a professional pH tester, which we calibrated just before testing these inks. As a quick chemistry refresher, a pH of 7 is neutral like distilled water. The closer you get to 0, the more acidic the ink is. The closer you get to 14, the more alkali/base the ink is.

Surprises are the most enjoyable parts of these tests. Blues remain entirely unpredictable. One of my all-time favorite blues is Parker Penman Sapphire. Instead of fading out like most blues, it turned purple! Visconti blue fades out when thinly applied, but the thicker lines create a majestic blue-black that is even prettier than the original blue. Colorverse Quasar turned from a rich blue to a light red-purple. Omas blue did what most blues do and faded heavily. Acidity didn’t seem to effect which brands faded and didn’t. Omas was the most acidic blue at 2.3, and Colorverse was the most neutral at 7.9. Both underwent dramatic changes.

There were subtle changes in some of the inks. Visconti’s black turned a dark brown in the sunlight.

Purples fared poorly. Visconti Purple turned a pale pink. Vintage 1960s’ Waterman’s Violet almost completely disappeared. Pelikan Violet held on kinda, turning a deep reddish pink.

Waterman’s Red and Omas’ Red/Burgundy held up best. Neither seemed very effected by the sun. Also interesting was that Omas’ ink was also almost pH neutral at 7.2. We are often warned red can be the most dangerous color to put in a fountain pen. If it is pH neutral, I wonder what chemical reactions happen when it is inside a pen.

We had never previously heard of Francesco Rubinato inks before, but we loved the “Verde” green ink that was somewhere between “Shamrock Shake” and “Kelly Green.” Unfortunately, it turns into a bile-like yellow green with UV exposure.

An OLD bottle of Rotring Red was a very curious color. It was more of a brick red with a hint of orange. Was that because it was already discolored and UV exposed or was Rotring red really like that? Either way, UV didn’t effect the dry ink on the page.

The only color not yet mentioned is the Francesco Rubinato Oro (gold). This is a goupy, heavily sedimented ink filled with gold-glitter. We DO NOT recommend it for fountain pens. It is ONLY GOOD for DIP PENS. Anyhow, UV light didn’t effect it at all, and because we didn’t want to ruin our pH tester, we didn’t check its pH level, either.

Here is the table of our pH results:

Visconti Black…………………………..4.2
Visconti Blue……………………………3.9
Visconti Purple…………………………3.2
Parker Penman Sapphire…………..5.3
Francesco Rubinato Verde…………4.1
Omas Red/Burg………………………..7.2
Omas Blue……………………………….2.3
Rotring Brick Red…………………….8.5
Waterman (1960s) Violet………….3.9
Waterman Red………………………..5.9
Colorverse Quasar…………………….7.9

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.)

A 3-Month Ink-Fast Test

A gentleman at this year’s Chicago Pen Show showed me his very elaborate ink-fast test to see which of his inks could best withstand direct sunlight for an extended period of time. He tested dozens, if not more than 100 inks, to see how they looked new, at 3 months, at 6 months and a year.

As he said most of the damage was done to the ink within the first three months, I decided to try a 3-month ink-fast test on my 8 favorite inks.

8 inks testing day 1

Here are the fresh fountain pen inks on Day 1 of the trial before being placed in my sunniest window.

Hopefully the photos show the results. However, to clarify any difficulties due to all of the variations of computer screens, I shall describe the results, as well.

Lamy Green went from a bright kelly green a faded, almost camouflage green-grey.

Lamy Turquoise turned to a blue-black.

Monte Verde’s new blue fountain pen ink faired second to worst, turning from a nice medium blue to a light shade of grey.

Parker Blue-Black fared best, maintaining a strong dark color more black than blue.

Waterman Florida Blue turned medium grey.

Pelikan Edelstein Adventurine, which is almost a forest green, but not quite, turned turquoise.

Aurora Black Ink turned a medium to darkish brown. This made me wonder if Aurora put a touch of iron in its ink.

Inks after 90 days of sun

After 90 days in direct sunlight, all 8 inks faded. However, it appears that Parker Blue-Black ink held fastest and Yard-O-Led Royal Blue faded the most.

Yard-O-Led Royal Blue, which is an especially brilliant blue when fresh, fared worst and turned to a barely legible sky blue.

Although I had no idea how Waterman Florida Blue would deteriorate over the years, it has been my go-to ink since I discovered it in the 1990s. Now that they no longer make it and changed the formula to Parker’s slightly inferior blue Quink, I am on a quest for a new blue to love. I thought Yard-O-Led would be it, but now I have my doubts. A German friend has turned me on to Diamine Kensington Blue. We’ll have to see how that holds up to the sun.

When I know, I’ll be sure to share.

Sanford Ink: A Brief History

If you troll the antique stores of America searching for great deals on vintage pens, you cannot help but come upon those seemingly ubiquitous small pressed glass ink bottles by Sanford. They have myriad colored caps. Maybe you run into the Sanford Pen It inkwells and towers.

The Sanford Ink Company is one of the oldest ink companies in the world that is still in operation. They made many colors of fountain pen inks since 1857, and they invented the Sharpie in 1964! This Sanford Ink display is a metal carousel that is most likely from the late 1940s or early 1950s.

The more I found, the more I asked: Who and what was the Sanford Ink Company? Why aren’t they still around? Did their ink perform so terribly that they went out of business…just not before making billions of bottles of ink to litter our antique malls?

My ignorance got the better of me a few months ago when I was asked to sell a display carousel of those little cubed 1oz ink bottles. It had close to a dozen different colors on an aluminum spinner that appeared to be straight out of the late 1940s or early 1950s. I finally had to breakdown and research the company if I had any prayer of selling this thing. It was perhaps my happiest discovery about the ink world this year.

Sanford inks didn’t suck. They are so good that they are still the bestselling in America today. They just don’t sell fountain pen ink any more. You will better know their universally famous product: the Sharpie Marker. With its nearly indestructible permanent black ink markers and other colors, Sharpie is in nearly every home and office.

The Sanford story is actually a very interesting one. Sanford dates all the way back to 1857, before the Civil War. They made ink and glue in Massachusetts before moving to Chicago in 1866, just 5 years before the great fire burned the city to the ground. Sanford actually survived the tragic fire only to be burned down by another blaze a very short while later. The company rebuilt and became one of America’s largest ink manufacturers and suppliers by the end of the Great Depression. The only ink company we know that has been in the game longer is Pelikan, which got its start in Hanover, Germany, in 1838.

The Sharpie marker can write on most any surface with a permanent ink. This older Sharpie still shows the Sanford coporate logo.

The invention of the ballpoint pen during the 1940s spelled doom for the fountain pen (and ink) industry. By the 1960s, the Sanford Ink Company was looking to emerging markets to find a new product to keep the company afloat. The Sharpie marker was born in 1964—50 years ago this year! It could write on glass, paper, rocks, just about any surface. It was quickly endorsed by late night talk show comedians Johnny Carson and Jack Paar.

These days it is the “pen” of choice by many star athletes and performers for signing autographs on everything from footballs to glossy photos. Roughly 200 million markers are made every year, according to the Sharpie website.

In a bizarre twist of pen fate, Sanford was bought by Newell Rubbermaid in 1992. Newell Rubbermaid also owns the brands: Parker, Waterman and PaperMate. So, in a sense, Sanford has never fully left the fountain pen ink business. It is now owned by the same people who own what would have been some of Sanford’s greatest competitors 60 years ago.
