Cyanotype toning

Works great with cyanotypes. I use 10 grams to 2 liters of lukewarm water and tone the photos for about 30 minutes for a deep rich color. Mixes well.

Used this as an alternative to tea and coffee to tone my cyanotypes. Works great, without staining the paper. Gives a reddish brown color, if toned without sodium carbonate bleach first. With sodium carbonate bleach step, more of a straight brown (but shadow and highlight details disappear...not to my liking)

question
Can this Tannic Acid be use tone cyanotype prints? If so, what color does it turn the print?
Tannic Acid does in fact tone cyanotype prints. If toned straight in a bath of tannic acid it will darken the print give it more of a violet/purple tone. There are a variety of toning combinations that use this, and I recommend the Book of Alternative Processes by Christopher James if you're interesting in more.
