How to distinguish cinnabar! What is commonly used?

Zhu Shashi, also known as mercury sand, cinnabar, Danli and Chidan, is mainly produced in Wanshan, Tongren, eastern Guizhou. Zhu Shashi, formerly known as cinnabar, was named after its earliest discovery in Chenzhou (now Yuanling), Hunan Province. It is the main raw material for smelting mercury. There are as many as 50 proven cinnabar producing areas in Guizhou province, and the cinnabar production in the border area between eastern Guizhou and Hunan accounts for 80% of the country. Wanshan cinnabar is rich in reserves, excellent in quality, bright red in color, huge in particles accompanied by surrounding rocks, radiant and excellent in ornamental value. It has been listed as a tribute since the Tang dynasty and has been famous all over the world for thousands of years. This stone is moist in texture, ingenious in shape, red and white in color, gorgeous and dazzling, and the surrounding silvery rock crystal clusters are dotted with red crystals, which constitute the picturesque beauty of Yushu Qionghua, the sunset snow scene, the hidden treasure of the Crystal Palace and the rising sun in the East China Sea.

The chemical composition of cinnabar is mercury sulfide, and its color is often bright red, vermilion, light red, dark red and streaky 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, high brittleness and cleavage development; 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.

1June, 980, a huge crystal cinnabar was collected in Yanwuping mining area, Wanshan, Guizhou. The crystal is 6.54 cm long, 3.5 cm wide, 3.7 cm high and has a net weight of 237 grams. It is pure and flawless, bright red in color and complete in crystal form. The bedrock on one side is dolomite crystal clusters, which are red and white, colorful and magnificent. It is a rare treasure in cinnabar.
