My ink-testing procedure is to write, blot and swab the noxious substance on a Clairefontaine index card and also write the name of each ink in a notebook, always using the same dip pen. Then I rinse and dry the nib. This process has worked well until now: firstly when I opened my bottle of Diamine Calligraphy Passion. The flow was bad but I got the job done. Next I indexed three inks which had normal flow.
Papier Plume Heart of Gold is an orangey/coral colour ink created for the Pay-it-Forward Project on Kickstarter. Heart of Gold would not flow! I could only write a few letters before the tip dried, despite a blob of ink on the nib’s cutout. Normally ink here should flow down the slit to the tip of the nib. Mm-hmm. This is what we call a dry ink. I had to complete the entry with a glass nib, which wrote well enough, but then cleaning the nib was a problem. The ink stuck to it, (!) taking a few rinses to wash off. This may be because the ink is partly water-resistant. (Of course other permanent inks are mostly well-lubricated.)
Given the shading on the swabs and ink blots, Heart of Gold would be interesting in a folded nib. If I try that then I’ll put a picture here.
Anyway, the other six inks were fine! Robert (Cult Pens Iridescink) bled through a Field Notes (Pitch Black) notebook page and has a shiny green sheen.
Krishna Anokhi also has a green sheen but it is matt, not shiny. Oster’s Fire on Fire, Cult Pens’ Deep Dark Green and Orange were all excellent but I was most taken with Diamine’s Smoke on the Water — a smooth deep turquoise with a red outline/sheen:
PS: Other reviewers had no problems with Heart of Gold but a couple remarked on the dryness:
