Q: 1. How many rolls can I develop with this? Also how easy is to mix smaller amounts - let's say 1L at a time? Thanks

Q: 2. Title says "Card Stock" but Key Features says "Easy-Folding Paper" I am looking for a card stock to keep photo in sleeve from bending. Which is it?

Q: 4. Can this Tannic Acid be use tone cyanotype prints? If so, what color does it turn the print?

A: 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.
