** We are currently out of Ferric Ammonium Citrate, green flakes! The brown flakes have come in. This is Solution A in the Cyanotype kits. As of 10/7/2020 our ETA for green flakes is about 6 weeks. All kits will contain brown FAC flakes for the time being**
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 containter, dipping a wet synthetic sable hair brush into the mixture, and "painting" the solution on to the paper using multiple brush strokes.**
