DiamineRegistrar's Bottled Ink 30ml - Blue/Black

Great for my work

(Written by Brenda's husband who still writes manually with a fountain pen) I've been meaning to get some for ages and when I finally got a round tuit, I was not disappointed. When you first start to write, it is as stated of a pale milky blue colour. Depending on the sort of paper that you write on, the ink quite quickly darkens in colour to an intense blue-black. It is only a matter of minutes though the final full effect could well take an hour or longer. The exact finished product seems to depend on the paper used. Some producing a blue undertone whilst I noticed that standard, computer printing paper had a mauve undertone. I wrote something on some very highly glazed paper, probably heat treated and it remained the initial blue colour. 15 hours later it looked like some standard blue-black ink that had been heavily diluted. I would thus suppose that the main agent for producing the full blue-black effect must be a reaction with the cellulose in the paper. The writing on the glazed paper was left in the light which seemed to be having very little effect. I shall enjoy further experimentation but the omens are that if you use traditional unglazed paper, you should meet with no problems and be well satisfied with the end result.

As a sketcher I was really looking for something waterproof and, ideally black. Noodlers Bulletproof was quite a bit more expensive so I thought this Blue/Black would be a dark enough ink to work. Unfortunately the ink is just blue. Perhaps a hair darker and less saturated than blue blue ink but still undeniably blue so not suitable for sketching. If used with a dip pen, you can get it thick enough to appear somewhat black (but if you're using a dip pen then you're better off with India ink or similar)

I use it for Wedding registers etc. Not a lot you can say about ink. Just normal Registrars ink which I use in a fountain pen. Do thoroughly rinse the pen clean after if you are not going to use it frequently it can dry and clog up I was advised

Arrived ok and appears to work well, unless I leave something for years won't know if it does the job. In use daily, so far so good.

I bought this ink as I am a wedding registrar. When I first used It I was worried as it writes in a greyish colour but as it dries it turns much darker. It might have been my imagination but it also seemed to write more smoothly than my other inks. As with most permanent inks I believe it contains iron so I wash my pen out after each wedding and refill a few days before. Highly recommend.

Highly waterproof ink, which darkens from blue to darker blue or black, depending of time and amount of ink. Perfect for lasting writing without using pigmented ink, which might clog you pen easier; that I know of experience.

Watch what you write with this ink... literally - watch as it goes on blue and then dries black. Fun - eh?Also - watch what you write too, because once it's in your registers it'll be there for hundreds of years... mind you, I won't be there to check that claim and neither will the manufacturers but I guess we take their claims on trust...
