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). In addition, HgS is found in a black, non-cinnabar polymorph (metacinnabar) that has the zincblende structure. [5]
Cinnabar moths are about 20 mm (0.79 in) long and have a wingspan of 32–42 mm (1.3–1.7 in). Cinnabar moths are day-flying insects with distinctive pinkish-red and black wings. There is little variation in patterning, although on rare occasions the red markings may be replaced with yellow, or the forewing is entirely red with a black border ...
In 1835, "Chinese vermilion" was described as a cinnabar so pure that it only had to be ground into powder to become a perfect vermilion. Historically, European vermilion often included adulterants including brick, orpiment , iron oxide , Persian red , iodine scarlet —and minium (red lead), an inexpensive and bright, but fugitive lead-oxide ...
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.
The Jin dynasty Daoist scholar Ge Hong's c. 320 CE Baopuzi (Master Who Embraces Simplicity) is the earliest surviving source of information about zhi excrescences.. Based upon no longer extant texts and illustrations, Chapter 11 (仙藥; Xianyao; "Medicines of Immortality") outlines folklore and knowledge about zhi, and elucidates the wuzhi (五芝; "Five Zhi") classification system.
Dry leaves, along with dry grass, dead plants, wood chips, shredded paper, and sawdust are examples of carbon to place in the compost. Oxygen or green material includes grass clippings, produce ...
Zygaena trifolii, the five-spot burnet, is a day-flying moth in the family Zygaenidae found in North Africa and Europe. It was described by the German zoologist Eugenius Johann Christoph Esper in 1783 from the type specimen found in Frankfurt am Main , Germany.
Widely distributed in Eastern Northern America, it can be found from June to October, mostly on the ground in broadleaf and mixed broadleaf/conifer forests. It usually occurs scattered or in small groups. [5] It forms mycorrhizal associations with forest trees and shows preference for acidic soils. [6]
