Cinnabar, also known as cinnabar, is formed by volcanic action and natural weathering. The cinnabar of exogenous origin occurs in the lower part of the oxidation zone and is decomposed from tetrahedrite

The genesis of cinnabar is related to modern volcanism and is a typical low temperature hydrothermal mineral. The chemical composition of cinnabar is mercuric sulfide, containing 86.2% Hg, and often containing clay, iron oxide, asphalt and other impurities. It is soluble in hydrochloric acid and proces hydrogen sulfide with rotten egg flavor

extended materials:

for a long time, vermilion pigment made of cinnabar is one of the favorite colors of painters, but with the passage of time, vermilion will become black. Researchers have found that the reason is that cinnabar exposed to the air forms mercury under the action of light and chloride ions, Scientific American reported

the main component of cinnabar is mercuric sulfide, which can be broken by a series of chemical reactions of chloride ions, and this phenomenon exists in the air near the sea by the action of light. The final proct of this chemical reaction is pure mercury, which may cause the painting to turn from red to black
