@jimp Oh neat, I'd thought that was pigmented, but apparently not. Coincidentally I have some on the way.
@johns I have looked up on the internet while was asked exactly this question, and have found this results (by mostly looking on Mountain of Ink blog):
- Aurora Black is very often recommended as the darkest black.
- Cross Black is also to me very dark and rivals Aurora on the same blog.
- Lamy Black looks very dark and close to the two above and I have personal experience with that. It works in my Platinum Preppies/Prefounte EF (0.2mm) nibs and delivers very consistent dark lines.
@johns I really like Iroshizuku Take-Sumi. Good deep black, writes and dries well with the pens I use it with. Not compared it with many other black #FountainPen inks except standard Pilot black , and it's certainly nicer and blacker than that, to my eye.
@johns I like Graf von Faber-Castell Carbon Black

Not sure it's the darkest, but it's good
