This Cyanotype Kit makes sun printing easier than ever and includes everything needed to get started. 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 the included 300g Hahnemuehle Platinum Rag Fine Art Paper with the sensitizer and, once dry, create prints by exposing to sunlight or UV (10-20 minutes, depending on conditions), using objects and the included glass printing frame or a film negative to create an image. After exposure, prints are processed in a tray of cool water and allowed to air dry. The kit comes with enough material to make at least a dozen 8.5" x 11" prints.
