A catalogue of pigments printed around 1840 lists a green oxide of chromium, which is believed to be chromium oxide. Chromium(III) oxide also known as Chromic Oxide is the inorganic compound of the formula Cr 2 O 3. The reason for this is that a natural oxide would not fit the FDA requirement for the minimium in heavy metal contents. Also, in 1969 Kühn, using microscopy and emission spectroscopy, found chromium oxide in three paintings which dated between 1845 and 1850. Its colour intensity is too strong to be used directly on the skin and it should be used sparingly as a colour additive to a recipe. Clickhere for theTechnical Data sheet It can be used to refer to a mixture of chrome yellow (Lead Chromate) and Prussian blue (Ferrocyanate).
