Cobalt blue chromate

Pigment green 50 is a niche player as well. Its relationship to phthalocyanine green parallels that of cobalt blue to phthalocyanine blue. Its opportunities are further constrained by chromium oxide green, which offers similar but not quite comparable performance properties and a similar but less chromatic and dirtier hue at about one-seventh the price.

Cobalt Nitrate, Co(N03)2.6H20. Soluble cobalt compounds sometimes used in the ceramic industry for the purpose of neutralizing the slightly yellow colour caused by the presence of iron impurities the principle is the same as the use of a blue bag in the laundry. Cobalt Chromate, CoCr04. Finds some use, in admixture with ZnO and AI2O3, as a green or blue colour for vitreous enamels. 

The German author Jamiicke (1893) discusses blue oxide and green blue oxide Blauoxyd and Griinblauoxyd ). Blue oxide is described as a cobalt chromate green blue oxide is seemingly a mixture of cobalt and chromium oxides. 

The German author Jannicke (1893) describes blue oxide as a cobalt chromate. Little is known about this compoimd as a pigment. It may have been confused with Turkish green q.v.), however a chromium cobalt oxide (CoCr204) is described as a green pigment in the Merck Index (1996). 

Other cobalt compounds with chromium have also been used as pigments (see chromates group). Additionally, smalt, a cobalt-doped glass, has been an important blue pigment.
