Diamine graphite

It's great ink, but a little more on the pure grey side. I was hoping for something a little darker.

A nice Grey-Green ink

I was not initially impressed with the color, hoping it would be a darker grey, but after using it some more, it has grown on me because it has a green hue.

It's like liquid pencil!

Like the title says. It's a dark grey that in a normal pen looks like pencil lead. A super wet writer will look black.Manners are great, no feathering, quick drying, a little shading. If you want a grey ink, this one is plenty dark enough for professional use. Just a cool color.

My unexpected favorite ink!

I bought this sample on a whim because I heard it looked like pencil when written and i thought that sounded sort of odd. I ended up loving this ink and it's now one of the two inks I use in my pens at work. The shade of grey when it dries is bright and clear, with just the right amount of contrast against the page.

Has a very noticeable olive greenish cast

This is definitely not a neutral gray, as it has a very noticeable olive greenish cast/tint to it. However, like all Diamines I've tried it is very well behaved and a great value, especially in the 80 ml bottle. Personally, I strongly prefer the perfectly neutral gray color of Diamine Grey, but the aforementioned olive greenish tint of Diamine Graphite makes it a *perfect* match for the LAMY Safari, Charcoal if you enjoy matching your inks to your pens. Oh, and to me it seemed like Diamine Graphite is a bit less wet (and maybe dries even more quickly) than the other Diamine inks I've tried thus far.

FAQ about Ink Samples

How do I fill my fountain pen from an ink sample vial? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

It depends on the fountain pen's filling mechanism.

Check out our blog post on How to Fill a Fountain Pen from an Ink Sample Vial.

How much writing can I do with 2ml of ink? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

It really depends on how big or small you write, and the nib size you’re using. We find that usually you can get 2 good fills for a typical converter with our Ink samples, or one good fill with a piston-filling pen. How much writing depends on you more than anything else, so we recommend experimenting with different nib sizes to find what works best for you. 

What is shading, sheening, or shimmering ink? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

Shading - A common (and often desired) result of a fountain pen ink pooling in certain parts of a letter when writing, so that the color and saturation of the ink appears different within a single letter or word. This characteristic cannot be achieved with ballpoint or rollerball pens and is a very appealing aspect of fountain pen use for those particularly drawn to all the pretty ink colors.

Sheen - Characteristic of a fountain pen ink where when ink pools another color can be seen on top of the ink, especially when looked at in different light angles using certain paper types. There is no way to guarantee an ink will sheen, but using a larger nib on a pen will help obtain sheening results in your writing.

Shimmering - Fountain pen ink that has small particles of glitter mixed in.

Is shimmering ink safe to use in fountain pens? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

Yes! Shimmering ink is a great way to add some flare to your writing. We have found that a larger nib will showcase more shimmering particles while writing, but you can use any nib size and shimmering ink. All the ink we sell is safe for use in fountain pens.

You can learn more in our blog: How to Write with Shimmering Ink.
