Dilute 1 + 5 for most films. Can be used up to 1 + 10 dilution. Fix for 3x the clearing time, in most cases 5 minutes. To protect the stain produced with pyro developers, you have to use an alkaline fixer. Acid or rapid fixers will remove the stain produced by pyro and change the film to a normal negative instead of a stained negative.

The classic cyanotype formula consists of two solutions: 25% Ferric Ammonium Citrate in solution A and 10% Potassium Ferricyanide in solution B. Cyanotype prints produce images rendered in brilliant Prussian Blue. Create dream-like blue images on paper, fabric, or whatever else you can paint the emulsion onto. Great process for first-time printers! Coat, dry, expose and rinse with tap water. The 2x 100ml kit will make about 80 8″x10″ prints.
