Iron gall inks have been in existence for many hundreds of years, but most were for dip pens only. However, with the advent of the fountain pen, at the turn of the last century, came fountain pen safe iron gall inks as well. Iron gall inks are waterproof, and have been proven to stand the test of time despite their acidic nature (can eat through some papers over the course of several decades). Diamine Registrar’s Blue is a fountain pen safe traditional blue-black. It goes down blue and quickly begins to color shift to a very dark almost black sort of color. Here is a picture of the color shift:

When I first attempted to use this ink I experienced a near immediate clog. When I filled my pen, I had dipped it all the way to the bottom of the bottle. Iron gall inks tend to have a lot of sediment in comparison to conventional modern fountain pen inks, so I likely sucked some of that sediment into the pen. I flushed the pen without much difficulty, and filled it again with this time not dipping the pen too deep into the bottle. The second time worked out just fine, and I had no clogs. This potential for sediment and the acidity of the ink put iron gall inks in the high maintenance category. In my opinion, this ink is worth the extra effort.
- No feathering or bleeding. This ink performs admirably on poorer quality papers.
- Flow and lubrication are pretty good, but iron gall inks tend to run a bit dry. This ink is no exception.
- Drying time is a bit long with a wet writing pen.
- Excellent shading.
- 100% waterproof!
This ink was sent to me for review by the good folks at Diamine Ink Co. I am not otherwise affiliated with them.
PS: I just wanted to thank everyone for their thoughts and prays. I have made it back from my trip to see my grandpa. He is stable, but not doing well at all. I’m just glad I got a chance to spend some time with him before it was too late.
