Prussian blue has been used as a pigment in industry and for artists since 1704.
Prussian blue has been used as a treatment to speed up the excretion of
radioactive cesium or non-radioactive thallium, from the body according to
studies reported in the literature.(source:

Prussian Blue has several names. The original name of the pigment came from its use as a dye in the German Army uniforms. The name of the pigment had different names due to the different locations of its manufacture, the process of the manufacture itself, the result of varied physical properties, or the components through which it originated. The generic name for Prussian Blue is iron blue. Iron blue has a variety of hues due to the different processes of manufacture. Some of its commonly used names include Hamburg Blue, Paris Blue, bronze blue, celestial blue, cyanine, Haarlem blue, oriental blue, and potash blue. The general pigment code is CI Pigment Blue 27. Since Prussian Blue has two formulas, then the pigment code varies for each formula. The code for Fe4[Fe(CN6]3 xH20 is CI no. 77510. The code for KFe[Fe(Cn)6] xH20 id CI no. 77520.
