Vanness Pens x Robert Oster Hemp Fountain Pen Ink Review

It takes a lot to get me to like a green ink.

Akkerman #28 Hofkwartier Groen is far and away my favorite, and is a top five personal ink, regardless of color. The green is bright, no doubt thanks to a hefty dose of yellow in the mix, and shades wonderfully. It’s flat-out fun to use.

Well down the line after that shade comes the classic Rohrer & Klinger Alt-Goldgrun, primarily because it is weird as heck, and shades like a beast. It’s one of those inks that once you see it in person you know you have to have it. Faber-Castell Viper Green is a more traditional shade of green, but has an electric/searing nature in its tone. This would fall into an everyday writing green, but with a bit of an edge.

That’s mostly it for my green use, at least until I took a chance on Hemp, one of the three Vanness Pens collaborations with Robert Oster. This one is going into the rotation, most likely as my second green behind Akkerman #28.

Green inks are a short list for me, although I can’t explain why. Unlike blue, orange, or purple, green has to be a little weird for me to use. Traditional greens in the Kelly or Forest shades need not apply. Yellow undertones are good, which brings out the brightness, and having odd questions come to mind, like “What color of frog is this?” only serve to make it more fun.

Vanness Pens x Robert Oster Hemp Fountain Pen Ink Dry Time

I wasn’t sure what color Hemp would actually be. Was this to represent fresh growth, or in a processed for production phase? It’s definitely the former, with a good combination of established green in the middle, and the youth of yellow around the edges.

Vanness Pens x Robert Oster Hemp Fountain Pen Ink Writing

In my bank paper Musubi Notebook I saw more shading than I expected, using an Aurora Optima with a Medium gold nib. On Rhodia, the color was more flat, but bright (and had a loooong dry time.) On Tomoe River paper, the range of darkness showed up. The swab on the Col-o-ring Oversize is the best representation of the color that I see when writing with a nib.

The only remaining question I have at this point is how the ink will look on the page in one of my finer nibs. will the brightness and character still show up? I hope so, because I’ve answered the other important question - do I like this ink - already. And now I’m ready to use it more.

(I bought this ink from Vanness Pens at a discount.)

Robert Oster Carbon Fire Ink Review

Robert Oster Carbon Fire Ink Review

Over the past few months, I've definitely had a thing for trying new blue black inks. While I'm not tired of blue blacks, I decided it was time for something a little different. But don't get too excited — this next ink is just a shade or two brighter than the typical blue black. Despite being a close cousin of blue black, Robert Oster Carbon Fire is a spectacular dark blue that has just enough brightness to really lift my spirits.

While going through my ink and swatch collection to find comparable inks to Carbon Fire, I realized that I really don't have much at all in the blue spectrum that falls between bright, happy blue and blue black. Carbon Fire is the perfect dark blue that has an obviously blue hue while also being dark enough to seem "professional." To me, this is the color that most defacto "blue" that comes in gel, ballpoint, or rollerball refills. But, Carbon Fire has some extra qualities that set it apart from regular old navy blue.

Robert Oster Carbon Fire Ink Shading

For one, I'm a big fan of the amount of shading in this ink. It's not an intense level of shade between different blues, but it's enough that you can see it with small nibs. Of course, the larger the nib, the more pronounced and beautiful the shading becomes. I love an ink that has a good amount of shading, and Carbon Fire really does the trick for me.

Another hidden quality that I've only been able to coax out when using this ink with a medium cursive italic (or anything larger) is a very subtle sheen. It's so subtle and hard to detect that I can't decide if it's more of a red or pink sheen. Despite being subtle, it's somehow quite deliberate when you're looking at the ink color as a whole. It's difficult to describe. The subtle sheen adds a level of intrigue to the ink because you can't quite put your finger on what makes the ink something a bit more than a standard blue ink. It's not shimmery, it's not glossy...what is it?! These were my internal questions while I was testing this ink. Only by holding the paper at the right angle against the light does the sheen show itself for what it is. It hides beneath the navy surface and adds a pleasant je ne sais quoi to an otherwise ordinary ink color.

Robert Oster Carbon Fire Ink Comparison

If you like ink colors that exhibit mysterious qualities, this ink is right up your alley.

Aside from the color, shading, and sheen, this ink is standard fare for Robert Oster. It's not dry, but not too wet. It's smooth when writing and behaves well in the pens I've tried. It dries in a fairly standard 15-20 seconds depending on how large and wet the nib is. I couldn't detect any feathering or bleeding, which is also something I've come to admire with any Robert Oster ink.

I picked up Carbon Fire as a sample because I was intrigued by the name and thought the online swatch example was unique for a dark blue ink. I'm glad I followed the intrigue, because I might have found a new favorite ink.

You can pick up your own bottle of Robert Oster Carbon Fire from your favorite ink retailers for around $17 (Vanness, Pen Chalet, Goldspotand JetPens to name a few).
