"Cobalt Chromite is used because of its excellent resistance to atmospheric influences"

Often replaces the historically authentic azure blue color Cerulean Blue (PB35, Cobalt Stannate) PB 36 Cobalt Chromite Blue-Green Spinel), in some cases even claiming that this version is "authentic", however, C.I. Pigment Blue 36 is not the traditional pigment called Cerulean Blue PB-35;

Cobalt-chrome blue-green Co (Al, Cr) 2O4 is obtained by calcining at more than 1350 ° Celsius a mixture of cobalt (II) oxide, chromium (III) oxide and aluminum (III) oxide in various proportions, forming a crystalline spinel matrix. It may also contain one or more modifiers ZnO, MgO, SiO2, TiO2 and/or ZrO2 to adjust the color shade or other properties.
