Cinnabar, also known as cinnabar, cinnabar, red dan, mercury sand, is mercury sulfide from vermilion to brick red. Cinnabar is also historically the source of the refined, vermilion or bright red pigment. The color and character derive from the hexagonal lattice structure belonging to the trigonal crystal system, and the crystals sometimes exhibit twinning. For example, the natural pigments used in painting thangkas traditionally use precious mineral gems such as gold, silver, pearls, agate, coral, turquoise, malachite, cinnabar, and plants such as saffron, rhubarb, and indigo as pigments. embellishment.

The color is full of vermilion, and the color is more delicate. The price will be higher than that of purple gold sand.
Maintenance of cinnabar
The main component of cinnabar is mercury sulfide, but it is often mixed with realgar, apatite and other textures, and it is easy to dissolve and decolorize when it meets water. In addition, if cinnabar is soaked in water for a long time, if the texture is loose, it is easy to disintegrate, so when wearing cinnabar, try to avoid contact with water. In addition, cinnabar should not be directly exposed to fire, as it will turn black if it is directly burned. At the same time, if the cinnabar is heated above 180 degrees, it will be partially oxidized in an aerobic environment, and a small amount of mercury will be released.
