Cinnabar has a mean refractive index near 3.2, a hardness between 2.0 and 2.5, and a specific gravity of approximately 8.1. The color and properties derive from a structure that is a hexagonal crystalline lattice belonging to the trigonal crystal system , crystals that sometimes exhibit twinning .
Pycnoporus cinnabarinus, also known as the cinnabar polypore, is a saprophytic, white-rot decomposer. Its fruit body is a bright orange shelf fungus. It is common in many areas and is widely distributed throughout the world. It is inedible. [2] It produces cinnabarinic acid to protect itself from bacteria. [3]
Vermilion (sometimes vermillion) [1] is a color family and pigment most often used between antiquity and the 19th century from the powdered mineral cinnabar (a form of mercury sulfide). It is synonymous with red orange , which often takes a modern form, but is 11% brighter (at full brightness).
red cinnabar (α-HgS, trigonal, hP6, P3221) is the form in which mercury is most commonly found in nature. Cinnabar has rhombohedral crystal system. Crystals of red are optically active. This is caused by the Hg-S helices in the structure. [5] black metacinnabar (β-HgS) is less common in nature and adopts the zinc blende crystal structure (T 2 ...
The Wakasugiyama Cinnabar Mine (若杉山辰砂採掘遺跡, Wakasugiyama shinshasaikutsu iseki) is an archaeological site with the traces of a late Yayoi to early Kofun period cinnabar production site, located in the Suii neighborhood of the city of Anan, Tokushima on the island of Shikoku in Japan.

Cinnabar is the common bright scarlet to brick-red form of mercury(II) sulfide. Cinnabar may also refer to: Cinnabar, the color of the mineral; Cinnabar, Queensland, a locality in the Gympie Region, Queensland, Australia; Cinnabar moth (Tyria jacobaeae), a brightly coloured arctiid moth; Cinnabar Theater, a theater in Petaluma, California, USA
[2] The ancient Chinese believed that ingesting long-lasting mineral substances such as jade , cinnabar , or hematite would confer some of that longevity on the person who consumed them. [ 3 ] Gold was considered particularly potent, as it was a non-tarnishing precious metal; the idea of potable or drinkable gold is found in China by the end of ...
