DiamineFountain Pen Ink, Oxblood 30 ml

My favorite color from the diamine company. Dark, rich deep red. I rebought many times. Love the ink, love the company.

It is a nice light brown color. Works well in me Monteverde Monza pen

I have been looking for the 'perfect" green, something that resembles the fresh green of May leaves before they darken to withstand the sun's heat. I call that "May green". This ink is exactly that green. I am in absolute love with it and wish they would make a full size glass bottle of this wonderful ink. Needless to say, being a water based ink it is also water soluble as most inks are. Just thought I add that since I keep seeing this question coming up time and time again.

This review is for Diamine Oxblood.Expectations based off product pictures and other pictures were more of a brownish red similar to dried blood. Reality was that this ink came out much more brown than expected.The color is also more brown on paper than the color shown on the bottle or product images. Perhaps it is our choice of a fine nib. Scribbling a larger swatch, it does touch on reddish-brown, but still very much brown and nowhere close to the product image.As anyone who has done even basic research should already know, this ink does not at all hold up to water. Diamine inks in general seem to do very poorly when water gets involved. Bleed through on even normal notebook paper is minimal and no feathering with our writing speed which is fairly quick but sloppy. Slowing down for more legible writing does not cause issues with bleed through for us. Perhaps with a wetter pen/nib it might.We will keep this as a backup ink since it does write well and does look nice. Perhaps we can mix it with a brighter red and get the color where we want it.

I recently learned that most fountain pen ink is acid and will melt the silicone ink sacs in vintage pens. Diamine ink, however, is NOT acid. I don’t know what the PH is, nor do I know who tested it, but the good people of r/fountainpens highly recommended it.I love it. It sucks right up into the pen. The bottleneck is big enough that I can just stick the whole pen in (with the converter attached) and suction the ink straight up. Then the pen is primed and ready to go.I haven’t experienced any bleeding, and (ironically) the only time it has smudged is when I was writing this review. The color is really nice; it’s not an obnoxious orange, but more of an autumn color.For the price, you get a lot of ink. As someone who changes colors often, I’m glad I can just buy a little bottle that won’t go to waste.

This review is of the color Damson ink. (Amazon, please don't combine reviews of different products on the same page!) Also, the rounded glass bottle shown on the Damson product page is actually the larger bottle and is not what you will receive. If you order the 30ml bottle, it is a plain, tall rectangular plastic bottle. The ink is the same, just less of it, and the bottle isn't as pretty. I was expecting the bottle that is shown on the product page, but for the price, the smaller plain bottle is OK.I really like this ink. It flows well in my fountain pens and is not hard to rinse out of them. It's a pleasing, slightly smoky or muted purple, and a nice change from black and blue inks.Edit for an additional review of Diamine Amazing Amethyst ink:I've also bought a 30 ml bottle of the color Amazing Amethyst ink by Diamine. Amazon sent me an email wanting a review, but it linked to this review of Diamine Damson ink. Again, amazon, please don't combine reviews of different products on the same page!! Grrrr....Anyway, I like Diamine inks in general and both Damson and Amazing Amethyst in particular. The Amazing Amethyst is a brighter, richer purple, but still dark enough for most uses. In an average or wet-flowing pen, the color is very rich, deep, and jewel-like. I especially like it with a stub nib pen. I have one pen, though, that is a very dry writer, making this ink look washed out (but that pen makes every ink look washed out!) In short, both Damson (muted deep purple) and Amazing Amethyst (rich deep purple in most pens) are great inks.

Diamine Oxblood ink, is a beautiful ink. The color is rich and dark (if it spills on your hand it’ll look like you cut yourself, but on paper, it’s luxurious! A dark, deep burgundy—a true burgundy) and the ink dries rather quickly. I use a glass dip pen with this ink and it has made my writing experience even more of a joy!Now, I’ve used Rhodia and another brand of paper (I’ll edit this review and add the name later on when I remember), and there was no bleeding nor feathering, and little show through. Very high quality ink. I did not test to see if the ink is waterproof but I will check and edit the review when I can. Drying time? I’ll guesstimate under 10 seconds, far quicker than some other inks I’ve worked with. Diamine Oxblood is a well behaved, rich toned, great quality ink.On the other hand, if you are using a dip pen, I recommend you use a ink well (the bottle is small and narrow, so dipping the pen in it isn’t too “comfortable”..), but I this is a sample size, so I will be buying the larger bottle soon! I recommend this item!

I wanted this for both writing and sketching. The color is bold and dramatic, but not so flashy that you couldn't use it for every-day writing. It is not waterproof, so is lots of fun to blend with a brush and water after sketching. I used this in a very cheap fountain pen, and it flowed beautifully. I will be buying more Diamine Inks in the future.
