Jacquard's Cyanotype Kit makes solar printing easier than ever and this kit contains everything you need to get started. The liquid comes pre-measured in opaque black bottles. Fill each bottle with water to create Stock Solutions A & B, then mix the two in equal parts to make the cyanotype sensitizer.
Coat the supplied Hahnemühle Platinum Rag Fine Art paper with the sensitizer and, once dry, create prints by exposing them to sunlight or UV (10-20 minutes, depending on conditions). After exposure, prints are processed in a tray of cold water and allowed to air dry. The kit has enough material to make at least 12 (8.5x11in/21.59 x 27.94cm) prints.
