RE: Cyanotype toning and lead acetate.

My experience with toning cyanotype prints is that the alterations are
evanescent and not "permanent. If I am wrong, please someone tell me and I
will try to fix me and not the processes. Thanks. Joachim

To quote my own photographic cookbook: Cyanotype prints may be toned to a
deep ultramarine blue by immursing them in a 5% solution of lead acetate. (5
gm lead acetate in 100 cc water) Wear gloves and/or use tongs. Lead acetate
can be absorbed through your skin. Like all the heavy metals it is not good
for you, but it would take a lot more thabn a grain to kill you immediatly.
Wash the print afterward.

There is another process for toning cyanotypes that gives purple, brown and
blue tones. It was discovered by Judy and I have toned a lot of prints with
it.

Maybe if Judy is in a good mood she will post the process on the list. In my
cookbook I refer to it as Seigel Toning. I got the process from Judy. I have
never seen it published anywhere.
