Malachite is a copper carbonate hydroxide mineral, with the formula Cu 2 CO 3 (OH) 2. This opaque, green-banded mineral crystallizes in the monoclinic crystal system , and most often forms botryoidal , fibrous, or stalagmitic masses, in fractures and deep, underground spaces, where the water table and hydrothermal fluids provide the means for ...
Malachite green is also used in endospore staining, since it can directly stain endospores within bacterial cells; here a safranin counterstain is often used. Malachite green is a part of Alexander's pollen stain. Malachite green can also be used as a saturable absorber in dye lasers, or as a pH indicator between pH 0.2–1.8. However, this use ...
Both malachite and azurite, as well as synthetic basic copper carbonate have been used as pigments. [10] One example of the use of both azurite and its artificial form blue verditer [ 11 ] is the portrait of the family of Balthasar Gerbier by Peter Paul Rubens . [ 12 ]
A synthetic form of malachite, verditer, has also been used. In Latin America, the Teotihuacan civilisation, which ruled in Mexico between 300 and 650, AD, made murals using crushed malachite, which was mixed with chalk for lighter shades, or mixed with blue from azurite or lapis-lazuli to make blue greens, or with yellow ochre to make yellow ...

The malachite kingfisher (Corythornis cristatus) is a river kingfisher which is widely distributed in Africa south of the Sahara. It is largely resident except for seasonal climate-related movements. It is largely resident except for seasonal climate-related movements.
In his grand mansion in upstate New York, he had indoor plumbing (a luxury in 1840s America), a bathtub made of malachite and a toilet bowl made of Wedgwood, a fine English porcelain.
Malachite, a common ore of copper is primarily copper carbonate hydroxide Cu 2 (CO 3)(OH) 2. [2] This mineral undergoes thermal decomposition to 2CuO, CO 2 , and H 2 O [ 3 ] in several stages between 250 °C and 350 °C.
