Speaking of toning cyanotypes
We cannot let a day go by w/out recognizing "The World Journal of Post-Factory Photography", which, in Issue #7 has an article on page 36-38 by Judy Seigel about toning cyanotypes. It has most of the info you will need.
Here are my two formulae, not used or tried now for a few years. However I still have my print, made on a good quality cotton torn from an old bed sheet that is black, faded just a bit, but still black.
Brown-Black Toner
for Cyanotype (1)
Solution A 1 teaspoon tannic acid in one liter of water.
Solution B
2
teaspoons of sodium carbonate in one liter of water.
Immerse print dry or presoaked, but not
just right out of wash water from being made, into solution A for about two
minutes.
Wash
in clear water for about a minute.
Immerse
in solution B for less than a minute and rinse again.
Put
the print in solution A again and watch carefuly. Remove it BEFORE it gets to
the color you want.
Wash.
Brown-Black Toner
for Cyanotype (2)
Place
dry print in Ammonia solution ( 12.6 ml per liter)
When
bleached, place in Tannic Acid bath (23 gm per liter of water)
Wash
