Due to the ink tests, I decided that Diamine Twilight will be the next ink in my five-dollar Tachikawa manga pen, which may approximate the mix of original black ink and the Noodler's Navaho Turquoise I kept throwing into there.
Five days later, Dr. I. was still soaking and flushing that needle-nib pen that had been filled and never cleaned for ten years....water in cup still blue after one week's soaking. Ten years. Five days. I suppose it will take its own sweet time.
The first batch of blue-black testing, on Rhodia Uni:
The Diamine Prussian Blue looks greener than it is...the Tanzanite and Chopin look all to similar in this scan. I believe the Chopin is a little 'softer.' Thanks to KLP for both those samples!
Ooo...maybe I'll do a trio of chromas...
Which turned into a quartet. Diamine Prussian Blue shows turquoise in its corona. Edelstein Tanzanite washes into a royal blue, while Chopin plays it slate. The Skrip BB is from the conical Slovenia bottle and has a really interesting forest-green center. Dr. Inkenstein loves inks with complex chromas.
To be continued....soon.
