Ferric Ammonium Citrate a light-sensitive iron salt that is used with Potassium Ferricyanide to create sensitizer for Cyanotype printing. Cyanotype is an old photographic printing process that yields a cyan-blue print. Think of it as the SolarFast of the 1800s. The versatility of making unique prints is amazing. Print on any natural fiber including paper, cotton, silk, wool, wood and more.
To get a rough estimate on how much area these open stock chemicals might cover; the cyanotype kit (#JCSS) has about 2 ounces of Ferric Ammonium Citrate in it and it will cover a 5'x5' piece of fabric, conservatively. Keep in mind that more absorbent fabrics will take more solution.
