Cobalt(II) oxide is an inorganic compound that has been described as an olive-green^[3] or gray^[4] solid. It is used extensively in the ceramics industry as an additive to create blue-colored glazes and enamels, as well as in the chemical industry for producing cobalt(II) salts. A related material is cobalt(II,III) oxide, a black solid with the formula Co₃O₄.
