Malachite

Malachite is a copper carbonate with an OH group. Malachite generally has a green color, which can range from light green to black-green. It's opaque. It is most often in the form of powdery, earthy, layered, renal and stalactite aggregates. Occasionally also in the form of small columnar and acicular crystals. Its occurrence is linked to the occurrence areas of copper sulfides, such as chalcopyrite, which are converted.
Malachite has been used as a mineral pigment in green colors since antiquity, very sensitive to acids and color variations. In the 19th century, in areas with higher accumulation, it was used as a less important copper ore since it contains up to 55% to 57.4% copper. It was found on most copper deposits, formerly known as rock foliage.
The name of the mineral comes from the Greek word malache denoting mallow and a deep green color.
Previously, malachite was referred to as less pronounced copper ore. It has been treated as a precious stone since ancient times. Already in ancient Egypt, he had carved stones, amulets, and other ornaments from it. It was also known by the ancient Greeks and Romans. Crushed was used as a dye in painting or as a make-up.
