The topic of thinning inks in general and for technical pens in

I don't know that the thinness of the ink is necessarily the issue. The
Higgins and Rotring inks are already pretty thin, so it may be some other
factor. I also tried adding a little bit of detergent to the ink, which
didn't help. Maybe it's the carbon particle size, or clumping of those
particles? -- I really don't know.

In any case, I have a feeling that what I need is an ink that's made, in the
first place, to flow through fine points. I did receive one suggestion to
try Dr. Ph. Martin's "Black Star". Does anyone have any experience with
that ink? I'd hate to order a bottle and have another dud on my desk!

Regarding FPN, etc., they're fine, but by definition the focus is on
fountain pens and questions about other writing instruments can get lost in
the flood of posts. I thought I'd try this, more general, forum.
