The color of cinnabar is often bright red, vermilion, light red, dark red and striped red; The crystal belongs to the triangular system, which is plate-shaped or rhombic, and the aggregate is granular or massive. Diamond twin crystals and large-particle single crystals are common in crystal clusters. The surface has diamond luster, glass luster or metallic luster, translucent or opaque; High refractive index and brittleness.
The hardness is Mohs 2-2.5 and the specific gravity is 8.2. Its powder is red and can last for a long time. It was used as a pigment a long time ago. Zhusha stone only occurs in volcanic rocks, hot spring deposits, low-temperature hydrothermal deposits and fault breccia dolomite caves, and often coexists with Yingshi, Realgar, orpiment, calcite, stibnite, pyrite and albite.
brief introduction
Cinnabar, also known as ghost fairy cinnabar, cinnabar, red lead and mercury sand, is a kind of mercury sulfide (HgS) mineral. It contains 86.2% mercury and is the main mineral raw material for mercury smelting. Its crystal can be used as an important material for laser technology. It is also a Chinese herbal medicine with sedative, sedative and bactericidal effects. China used it as an important raw material for an alchemist in ancient times. In the past, Chenzhou (now Yuanling, Hunan Province) was named after the best quality.
