Darkest of all blue pigments, the first modern man-made pigment, developed in 1706 in Germany. As with other pigment innovations, Prussian blue was basically a serendipitous accident.Prussian court artists were using the pigment in 1710. The first famous painters to use it included Pieter van der Werff and Antoine Watteau; the pigment was taken up by Japanese painters and woodblock print artists. Produced by oxidation of ferrous ferrocyanide salts; not toxic because the cyanide groups are tightly bound to iron. Because it is easily made, cheap, nontoxic, and intensely colored (as shown by the stained storage jar), Prussian blue was adopted as a pigment very soon after its invention and was almost immediately widely used in oil, watercolor, and dyeing. Lightfast, stable, mixes with any pigment, but can turn black in some mediums, sensitive to alkalis and instantly discolored by potassium hydroxide.
