Cyanotype Set, Two Component Bottles

This set makes DIY cyanotype printing as easy as can be. The chemistry comes pre-measured in lightproof black bottles. Simply fill each bottle with water to create Stock Solutions A & B and mix the two in equal parts to create the cyanotype sensitizer. Coat fabric or paper with the sensitizer and, once dry, create prints by exposing to sunlight or UV (3-15 minutes, depending on conditions), using objects or a film negative to create an image. After exposure, prints are processed in a tray of cool water and allowed to air dry. This set contains enough chemistry to make approximately 65 8.5" x 11" prints on paper or 50 8.5" x 11" prints on fabric, depending on the absorbency of the substrate. The set includes Part A Potassium Ferricyanide, Part B Ferric Ammonium Citrate and instructions.

An antique photographic process distinctive for producing Prussian blue monochromatic prints. Developed in the mid-19th century, cyanotype was quickly embraced as an inexpensive method for reproducing photographs, documents, maps and plans (hence the enduring architectural term "blueprint").

Famously, it was also used by Ana Atkins and other field biologists for indexing plant specimens. The first photograms ever made! Cyanotype is a remarkably simple process that employs two inexpensive chemicals and sunlight/UV. Prints can be made on any natural fiber: paper, cotton, silk, wool, wood, etc.
