...A photographic method that uses the photosensitivity of iron(III) salts, also known as cyanotype. Invented in 1842 by the British John Herschel (1792-1871), it was widely used until around 1950 to reproduce blueprints for civil engineering, architecture, machinery, and other fields. Blueprint photosensitive paper is made by dissolving iron(III) salts such as iron(III) chloride, ammonium iron(III) oxalate, and ammonium iron(III) citrate in water together with potassium ferricyanide (red ferricyanide) on paper, then coating it and drying it. ...
