Contents: Part A (Potassium Ferricyanide) & Part B (Ferric Ammonium Citrate)
This set contains enough chemistry to make approximately sixty-five, 8"x10" prints on paper or forty, 8"x10" prints on fabric, depending on the absorbency of the substrate.

Notes
CAUTION: May cause skin, eye, or respiratory track irritation. Avoid contact with skin, clothing, or inhaling dust. If inhaled move to fresh air. In case of contact with skin or eyes rinse with water for 15 minutes.
CONTENTS ARE LIGHT-SENSITIVE: do not remove from bag until you are ready to make a cyanotype print or mural!
Here's how it works: when the cyanotype fabric is exposed to sunlight (3-15 minutes), a chemical reaction occurs. It won't reveal itself, though, until you put the fabric into water. Then it instantly turns blue! So how do you make a print or mural? Place objects on the fabric to block the light: anywhere the sunlight doesn't touch will remain white and leave an impression on the fabric.
Instructions: To prepare the print or mural for exposure, there are two options: either get it ready indoors and then carry it carefully into sunlight, or spread the fabric out in sunlight and lay the objects on top as quickly as possible. Anything that casts a shadow will produce an image: plants or leaves, toys, tools, stencils, stones, sand, feathers, paper cutouts, string, lace or doilies. You can even make prints of your hands by placing them on the fabric or full body prints by lying on the fabric for the duration of the exposure (be careful not to move!).
Exposures should be made during the middle of the day in direct sunlight. Exposure times may vary with conditions but are generally between 3 and 15 minutes. (Note: over-exposure is almost always preferable to under-exposure. The print should look bronze in color after an adequate exposure.)
After exposure, remove the objects as quickly as you can and submerge the fabric in water. This is when the magic happens: in water, the fabric will turn blue! To instantly develop the cyanotype to its final, deep blue color, add a splash of hydrogen peroxide to the water. Wash for at least 5 minutes, changing the water periodically, and then allow to air dry.
Cyanotype prints and murals are archival. Yellowing may occur, however, if the fabric is exposed to phosphates or high pH environments. Cyanotype printed fabrics should always be laundered in cold water using non-phosphate detergents. Use care while handling, as sweat and hand oils may also cause discoloration.
