Part A: Potassium Ferricyanide - A red iron salt.

Use with Part B: Ferric Ammonium Citrate for cyanotype. 

Harness the power of the sun to make detailed prints from virtually any object that casts a shadow: tools, toys, plants, leaves, stones, sand, string, lace, etc. Simply place the object on the sensitized surface and expose to sunlight (UV). Use a digitally-printed photographic negative (an inverted black and white photo inkjet-printed onto a transparency*) instead of an object to create full-resolution photographs on paper or fabric. Great for photographers, mixed media artists, printmakers, quilters, kids and more, the cyanotype process is easy, forgiving, quick, magical and fun. Capture the nuance of every shadow - a fun group activity for any age!
