Experimental Poke (Polk) Berry Dye for Cyanotype Tinting

[Raghu Kuvempunagar]

Started by just trying various paper scraps around to see how it would affect them and ... no effect whatsoever.

Startled that it has ZERO ability to tint my watercolor paper that i use for cyanotypes.

"Pokeberry does not work well on cotton, hemp, linen or other plant fibers"

"It seems to work best on wool, with silk turning out a coral color. The cotton cross ties in my skeins did not absorb any color at all. "

Tips For Pokeberry Dyeing on Wool - Botanical Colors

We're pretty obsessed with pokeberry dyeing right now for dyeing wool, making ink and just squishing them up and dropping them on paper.

So what you observed might not be out of place. However, you should try again after heating the juice without boiling.

I had hoped to tint the paper first and then expose cyanotype over the tint, but guess that's not going to work.

Maybe I will try putting a small portion in with the A+B mix and, if it doesn't coagulate or precipitate, see what happens.

Not sure what you are trying to do here. You want to tint the whole paper magenta and then print cyanotype over it or you want to tone cyanotype with it. If latter, it is good that it does not touch the paper. That way your highlights will stay white. You might want to try and see what happens when a printed cyanotype is treated with tit.

That was Oak Gall Ink; very different.

I had understood that the Declaration was written in pokeberry ink because there was a shortage of the desirable oak gall type -- but maybe I heard/read wrong. Oak gall is so permanent that it's responsible for the whole concept of a palimpsest -- a document that's been erased (scraped, on parchment or vellum) and overwritten but the original writing is still readable with care -- so fading of that ink wouldn't be a major concern for conservation of the original Declaration.

Either way, I can't think of anything other than sizing that would make watercolor paper impervious to pokeberry ink. Maybe there's more to making the ink from pokeberries than just boiling the juice?
