Today I'm reviewing Diamine Prussian Blue

A blue-grey or blue-black ink from the standard range, Diamine Prussian Blue is a nicely saturated colour with a vintage look to it. It’s darker, less green leaning and more saturated than Indigo, and it flows better and feels more lubricated when writing across the page.

Prussian Blue was the first modern synthetic pigment. It’s a dark blue pigment also known as Berlin Blue or, in painting, Parisian or Paris Blue. It’s prepared as a very fine colloidal dispersion because the compound is not soluble in water. Prussian Blue is also the traditional “blue” in “blueprints” and as the basis for “laundry blueing.” (Source - Wikipedia)

I filled my Lamy Safari and my Lamy NexxM converters with it. Then left them on my table for a few days. When I went back to the pens, they both started writing straight away. No hard starts. They didn't skip once.

It exhibited excellent shading and it didn’t feather or spread on any of the papers I used it with. It didn’t show through on the HP paper either. Although it showed through slightly on some the papers listed, it didn’t show through as much as the scans suggest, and you can easily write on the reverse of all of the papers I used it with.

It's not sold as a waterproof ink but showed some water resistance.

  • Flow Rate: Good - neither particularly wet nor dry
  • Lubrication: Good - felt smooth across the page
  • Nib Dry-out: Not noticed.
  • Start-up: Immediate.
  • Saturation: Saturated
  • Shading Potential: Shading seen especially with F nib.
  • Sheen: None noticed, though I’ve seen sheen in some pictures.
  • Show-Through:
    • Clairefontaine Crokbook
    • Field Notes
    • Hobonichi Techo paper.
    • Tomoe River 52gsm paper (not very much)
  • Spread / Feathering / Woolly Line: Not seen on any paper even Field Notes
  • Nib Creep / “Crud”: Not seen, even after over 1 week in the pen
  • Staining (pen): Not seen after several days - very easy clean-up
  • Staining (hands): Very easy clean-up off of skin.
  • Clogging: Not seen.
  • Water resistance: Not sold as waterproof, but shows good water resistance.
  • Availability: Available in 80ml and 30ml bottles plus cartridges from Diamine Inks web-site and many other outlets.

What a comprehensive review, thank you. This is one of my favourite inks.

Stunning how similar it is to Indigo. I still don't know which one I like better. Both are for my taste too chalky....

IMHO Prussian Blue is better. Indigo is not quite saturated enough for me, and leans more green.

Thank you Chrissy for your excellent review, as always :) I am a big fan of Diamine Indigo and have been considering Prussian Blue. Your review has certainly steered me in the right direction.

One of my favourite blues and Diamine inks. Friendly on the eye and instantly vintage looking.

 

Thanks for giving it some exposure showing it to others :)

You're right, yes it does. :) Not nearly as green as I first thought it might be.

You're welcome. :)

I have one bottle that I have received from a friend 6 years ago, used it a lot with a PFMII with a medium nib, it was a delight to use it with this ink. Now I use it in a Stipula Etruria with a B nib and it works outstandingly well.

Pens are like watches , once you start a collection, you can hardly go back. And pens like all fine luxury items do improve with time

For the #50shadesofbluechallenge (link to the hashtag on Instagram), a challenge over at the German PenExchange forum for July & August 2020, I inked up all my pens with all the 50+ blue inks I have. The snapshots might also be of interest to some here.

Diamine Prussian Blue reminds me of a paled-out iron gall ink, just like Diamine Indigo does. Prussian Blue is even less saturated and more greyish, but, as you can see in the close-ups, it can be quite appealing in all its weirdness, especially when it develops the pronounced rim/darker edge of lines.

I had it in a Pilot Décimo with a flattened (stubbed) medium nib.

I love this ink...very friendly and calm. Thanks Chrissy - excellent review. And thanks to Julie too...your pics are outstanding.

Wow, lovely! Between the total lack of feathering, solid water resistance, and somewhat subdued color, this looks like a great ink for a work/pocket carry pen.

      @Texas42 Thank you. I myself have recently had the experience of cleaning out a Wing Sung 699, in which the iron-gall ink has been sitting for six months. No damage to the metal piston rod (whereas, in a Wing Sung 3013 vacuum-filler, it would have been corroded, turned green, and contaminated the ink in mere weeks), but there was a ring of colour at the far end of the barrel that wouldn't budge, and I found it impossible to unscrew the filling mechanism to clean the interior wall of the ink rese

      Dang. You are a great friend!   One comment as a relative newcomer would be within the cleaning section: issues/differences in cleaning vacuum filler, piston filler in addition to cartridge/converter. I just cleaned out my Pilot 823 and while it wasn't particularly difficult I was a little paranoid about the drops of water that I could not get out. Perhaps this is something you are already including.   Anyway, great project and very thoughtful of you. I know it's a project fo

      Hi Smug Dill,   Nice project.  If it were me, I'd cover stuff like: - nib types available, i.e. styles, materials (SS vs gold), flex vs nails; - filling systems (I love the "thingie" comment) and how once can use them in practice (e.g. fill cartridges with a syringe); - pen body materials and their consequences (pen not balanced of too heavy and big for the hand); - and, whilst you've made it clear that you do not like vintage pens, a discussion of these beyond "I d

      Thanks for your input! Yes, not putting wood in the list of body materials warranting a mention was an oversight. I love pens with wooden bodies, but my main concern, or chagrin, is that I have not come across a wooden-bodied pen with a wooden cap that seals well. Actually, there is one, but it isn't really wood per se: the Pilot Custom Kaede's maple body is resin impregnated. All other wooden pens I have can dry out while capped and undisturbed; that includes several Platinum #3776 models.
