Azure as a colorant

Azure pigment

The pigment is obtained from naturally occurring azurite Cu 3 (CO 3 ) 2 (OH) 2 and is slightly toxic. In the 17th century, the artificial Bremen blue Cu (OH) 2 was introduced to replace it . However, since this is not lightfast and more toxic than azure blue, it could not prevail as a full replacement. From the 18th century onwards, the pigment copper glaze , basic copper sulfate 2 CuSO 4 Cu (OH) 2 is also known as mountain blue .

The use of azurite can be traced back to ancient Egypt , where, like in the Roman Empire, it was used as make-up. Later it was one of the most important blue pigments in painting of the Middle Ages and the Renaissance . It is still used in painting today, but due to its extraction it is one of the more expensive pigments .
