An observation on the phenomenon of flash dry ink.
I filled a normally unproblematic fine nib pen with one of my favourite colours Diamine Bilberry. Bilberry dries quickly on the page but its not what I would normally think of as a dry ink.
After pausing a moment for reflection while writing, the pen refused to restart. It required water dipping the nib to reactivate the flow. This happened several times, even after as little as a 30 second pause, that I had to declare the nib and ink incompatible.
Have you found any other inks that are flash dryers?
