Mercury(II) sulfide, HgS, adopts the cinnabar structure described, and one additional structure, i.e. it is dimorphous. [16] Cinnabar is the more stable form, and is a structure akin to that of HgO : each Hg center has two short Hg−S bonds (each 2.36 Å ), and four longer Hg···S contacts (with 3.10, 3.10, 3.30 and 3.30 Å separations).
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]

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 ...
[2] [3] The first recorded use of "vermilion" as a color name in English was in 1289. [4] [5] The term cinnabar is used in mineralogy and crystallography for the red crystalline form of mercury sulfide HgS. Thus, the natural mineral pigment is called "cinnabar", and its synthetic form is called "vermilion" from red lead. [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.
This course takes an innovative approach for learning about writing, rhetoric, and research in that the large majority of our work will revolve around reading, evaluating, and writing in Wikipedia. As part of this work, you will each become familiar with goals, policies, and practices for understanding and contributing to the Wikipedia community.
Crystals of cinnabar, crystals of barite, crystals of quartz, crystals of calcite : Wanshan Mine, Wanshan District, Tongren Prefecture, Guizhou Province, China, an example of material historically associated with Chinese alchemy. Chinese alchemy (煉丹術 liàndānshù "method for refining cinnabar") is a historical Chinese approach to alchemy.
