Malachite Malachite Malachite is a copper carbonate hydroxide mineral, with the formula CuCO(OH). This opaque, green banded mineral crystallizes in the monoclinic crystal system, and most often forms botryoidal, fibrous, or stalagmitic masses, in fractures and spaces, deep underground, where the water table and hydrothermal fluids provide the means for chemical precipitation. Individual crystals are rare but do occur as slender to acicular prisms. Pseudomorphs after more tabular or blocky azurite crystals also occur. The stone's name derives (via , , and Middle English "melochites") from Greek Μολοχίτης λίθος "molochitis lithos", "mallow-green stone", from μολόχη "molōchē", variant of μαλάχη "malāchē", "mallow".
The Malachite Box by critics and enthusiastically received by readers, including the general populace and the more sophisticated Soviet intelligentsia. Bazhov turned into one of the most famous writers in the Soviet Union. Strangers would greet him on the streets. The critics agreed that "never has the labour of miners, stone-cutters, teemers been celebrate in such a way, neither in verses, nor in prose", and that Bazhov managed to show the essence of the professional skill of the miners. Mikhail Batin complimented its uniqueness, and novelty in the contents and in the form. Favourable reviews on "The Malachite Box" appeared in "Uralsky Rabochy"
