Malachite
Composition and Properties of Malachite
Malachite is a basic copper carbonate with the chemical formula of CuCO3 · Cu(OH)2. It is not stable at high temperatures, its decomposition begins at about 200 °C. Malachite, as all carbonates, is dissolved by even dilute acids but is unaffected by cold solutions of hydroxides.
Names
Mountain green, Olympian green, Hungarian green, copper greenPG 39, CI 77492From French malachite, ultimately from Greek malachitis (lithos) “mallow (stone),” from malakhe “mallow”; the mineral traditionally so called from the resemblance of its color to that of the leaves of the mallow plant. From Online Etymology Dictionary
Preparation
The pigment can be prepared from the mineral malachite by grounding, washing and levigating the raw material.Malachite can also be prepared in the laboratory by a reaction of copper (II) sulfate and sodium carbonate. The artificial form is sometimes called green verditer.
History of Use
Malachite has been used in ancient Egypt, but despite its abundance, it was seldom used in European oil painting. The following graph gives the frequency of its use in the paintings of the Schack Collection in the Bavarian State Art Collections in Munich (1).An extensive listing of occurrences of malachite in paintings in several historical periods can be found in the blog post ‘Pigment: The unusual green of Malachite‘ by The Eclectic Light Company.Examples of use

Side by side with the production of metals, the Egyptians and the inhabitants of Mesopotamia perfected the arts of making glazed pottery... and the production of glass. ...vessels were baked in tall closed furnaces. "Egyptian blue" was made in Egypt by heating silica with malachite and lime... applied with soda as a blue glaze on faience, and the blue glass is also colored with copper. Some early... Egyptian and Babylonian blue glass are coloured with cobalt.

Of all the colors I ordered: the three chromes, the Prussian blue, the emerald, the crimson lakes, the malachite green, all the orange lead, hardly one of them is to be found on the Dutch palette, in Maris, in Mauve or Israels - [all contemporaries of Vincent, Dutch painters of the Hague School.] Letter to Theo, Spring 1888; as quoted in Vincent van Gogh, edited by Alfred H.

It has sometimes been suggested that the wall paintings carried out by the hunters in southwestern France in caves during the Ice Age are unusual and represent a flowering of the arts which died... [However,] early farming communities ...frequently carried out quite elaborate paintings on the walls of their houses ...they appear to have decorated themselves as well, and we find small pestles and mortars used for grinding pigments in the making of cosmetics on many of their sites. ...[A] search had to be made for suitable pigments, and this ...led mankind to the ores of at least two metals. Yellow ocher or limonite, and red ocher or hematite, commonly known as jeweler's rouge, are both ores of iron, while the green mineral, malachite, and the blue mineral, azurite, are both ores of copper. But ...occasionally sizable lumps of copper are to be found among the ores of the metal. It is therefore more than a possibility that man's first interest in metallic copper was aroused while he was ...searching for a suitable green pigment...

There, looking at her table, with the malachite blotting case lying at the top and an unfinished letter, his thoughts suddenly changed. He began to think of her, of what she was thinking and feeling. For the first time he pictured vividly to himself her personal life, her ideas, her desires, and the idea that she could and should have a separate life of her own seemed to him so alarming that he made haste to dispel it. It was the chasm which he was afraid to peep into. To put himself in thought and feeling in another person's place was a spiritual exercise not natural to Alexey Alexandrovitch. He looked on this spiritual exercise as a harmful and dangerous abuse of the fancy. Part 2, Chapter 8, p. 135
