Cyanotype is a photographic process which produces photo prints or images of a dark blue colour nicknamed Prussian blue. This process takes its name from the Greek "kyanos" which means "dark blue", in reference to the characteristics of this colour. The technique is related to the effect light has on the following two chemicals when mixed: Ferric Ammonium Citrate and Potassium Ferricyanide. In the presence of light, the mixture oxidizes and will take on a (Prussian) blue colour. Suitable for children aged 8 years and upwards
