cobalt green

Cobalt green, also sometimes known as Rinman's green or Zinc Green, is a translucent green pigment made by mixing cobalt(II) oxide and zinc oxide and heating. It was invented by Swedish chemist Sven Rinman in 1780. Although it is stable and can be safely mixed with other pigments, it is rarely used because it is a weak pigment for its cost.
