2 cu 3 (co 3) 2 (oh) 2 + h 2 o → 3 cu 2 (co 3)(oh) 2 + co 2 From the above equation, the conversion of azurite into malachite is attributable to the low partial pressure of carbon dioxide in air. Azurite is quite stable under ordinary storage conditions, so that specimens retain their deep blue color for long periods of time.

Azurite pigment typically includes traces of malachite and cuprite; both minerals are found alongside azurite in nature, and they may account for some of the green discoloration of the pigment. [ 1 ] : 26 The particle size of azurite pigment has been shown to have a significant effect on its chromatic intensity, and the manner of grinding and ...
Associated minerals include: rosasite, smithsonite, hemimorphite, hydrozincite, malachite and azurite. [ 2 ] It was first described in 1839 by Bottger who named the mineral for its zinc and copper content after the Greek όρειχαλκος , for "mountain brass" or "mountain copper", the name of orichalcum , a fabulous metal, mentioned in the ...
