The Jacquard Cyanotype Sensitizer Set includes instructions and premeasured chemicals that together create a UV sensitive solution for cyanotype printing. Cyanotype is the “original” sun-printing process, one of the earliest photographic techniques. Discovered in 1842 and distinctive for producing rich, Prussian blue monochromatic prints, Cyanotype was popular well into the 20th century as an inexpensive method for reproducing photographs, documents, maps and plans (hence the enduring architectural term “blueprint”) and famously, for making impressions of biological specimens in the field (“photograms”). Produce unique Prussian blue monochromatic prints Prints can be made on any natural fiber including cotton, linen, silk, canvas, wood, paper, wood and leather. Enough for approx 50 x (8” x 10”) prints Easy to use Avoid ingestion, inhalation and contact with skin.   How to Use 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! Simply fill each light proof bottle with water to create stock solutions and mix the two in equal parts to create the cyanotype sensitizer. Coat fabric or paper (not included) with the sensitizer in a dark room, and once dry create prints by laying objects or film negatives on top and exposing to sunlight or UV light.
