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]

Chinese alchemy (煉丹術 liàndānshù "method for refining cinnabar") is a historical Chinese approach to alchemy.
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.
The leaves are pinnately lobed and the end lobe is blunt. [8] The many names that include the word "stinking" (and Mare's Fart) arise because of the unpleasant smell of the leaves . The hermaphrodite flower heads are 1.5–2.5 centimetres (0.6–1.0 in) diameter, and are borne in dense, flat-topped clusters; the florets are bright yellow.

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 ...
