Language English (derived from German)
First Recorded Use Early 18th Century

History

Prussian Blue was accidentally discovered around 1706 by the paint maker Diesbach in Berlin, Germany. He was attempting to create a red pigment using potash and cochineal, but due to a contaminated potash (which had been in contact with animal blood), he instead produced a vibrant blue. The exact circumstances are debated, but it involved iron salts and ferrocyanide. It quickly became a popular pigment due to its intensity, permanence, and affordability compared to ultramarine. It was widely used in painting, textiles, and even as a medical treatment (for heavy metal poisoning). Its chemical formula is ferric ferrocyanide, Fe₄[Fe(CN)₆]₃.

First Recorded Use

Circa 1706-1707

Cultural Associations

Prussian Blue is famously associated with the uniforms of the Prussian army, giving it its name. It was a dominant blue pigment for over a century, influencing art from Rococo to Impressionism. Hokusai's 'The Great Wave off Kanagawa' is a prime example of its use in Japanese ukiyo-e prints. It also played a significant role in the development of blueprints (cyanotypes) due to its photosensitivity. In medicine, it's used as an antidote for thallium and radioactive cesium poisoning, as it binds to these ions and prevents their absorption.
