I didn't go to this years Atlanta Pen Show with much of a shopping list but one ink was definitely on the radar: Organics Studio Blue Merle. I assumed the Anderson's would have it at their table, and with an exchange of American currency a bottle was mine.
Organics Studio bills Blue Merle as a recreation of vintage Carter's ink. I'll admit I have no idea what Carter's ink is/was, but the goal was to create an ink with very few ingredients that behaves well and is easy to clean. In my testing so far, all of these things are true.
What drew me to Blue Merle, of course, is that is a blue black ink. Yet another one added to my collection! Blue Merle leans heavy on the grey side of the spectrum, making for a nice rain cloud type of color. Grey is one color I can handle in my blue black inks and this one is nice.
The behavior of this ink is a huge selling point. It flows great (I used my Pilot Custom Heritage 92 with a bold CI nib), shades wonderfully, dries reasonably fast, and cleans well. I've used it in a range of pens so far and have had zero issues wherever I have tried it.
In the grand scheme of things, Blue Merle probably will not crack my Top 5 blue black inks, but that's not a mark against it. It is a fun ink that is in the rotation often and always provides a great writing experience.
