Cyanotype is a beautiful prussian blue print process, first discovered by Sir John Herschel in 1842.
It uses two chemicals, Ferric Ammonium Citrate and Potassium Ferricyanide, that yield a monochromatic "Prussian Blue" print when mixed together.
Our Cyanotype kits are based off the traditional formula, come as two bottles with pre-measured out powders. To use, simply fill each bottle up to the top with water and give it a good shake!
For this process, we recommend using 100% cotton rag paper, muslin, or silk! Arches Platine, Revere Platinum, Hahnemuhle Platinum Rag, Hahnmuhle Sumi-E, and Rives BFK are very suitable choices for this process!
**A note on the Sumi-E, this is a paper that we sell only for Cyanotype. It is a paper that is best coated by mixing up a bulk mixture of Solution A and B in a large plastic or glass container, dipping a wet synthetic sable hairbrush into the mixture, and "painting" the solution onto the paper using multiple brush strokes.**
