abstract
  • Prussian blue is a very dark blue, colorfast, non-toxic pigment – one of the first synthetic dyes – which was discovered accidentally in Berlin in 1704. Its name comes from the fact that it was first extensively used to dye the dark blue uniforms of the Prussian army. It is an inorganic compound with the idealized formula Fe7(CN)18, containing also variable amounts of water and other ions. With several other names (see table to right), this dark blue solid is commonly abbreviated "PB." PB is a common pigment, the object of instructional experiments, and an antidote for certain kinds of heavy metal poisoning. Because it is easily synthesized in impure form, it also has a complicated chemistry that has led to extensive speculation on its structure. It is used in paints and is the "blue" in blueprints.
