Cobalt Oxide is used in glass, enamel, ceramics, color glaze and pigment, etc. 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. Water Solubility insoluble.

Cobalt oxide or cobalt monoxide is an inorganic compound that appears as olive-green to red crystals, or as a greyish or black powder. Though commercially available, cobalt(II) oxide may be prepared in the laboratory by electrolyzing a solution of cobalt(II) chloride.
The cobalt content is 71.5% in this grade, but other than sodium, the low metal impurity levels are maintained. This oxide is ideal for enamel frit applications requiring uniform fine powder free of hard agglomerates.
Cobalt(II) oxide has for centuries ill-used since a colorising federal agent on duty kiln discharged pottery. The additive provides a deep nuance of blasphemous named greenish blue. The band gap (CoO) is around 2.4 eV. It also is used in cobalt blue glass.
