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]
Obsidian and exotic shells have also been found in Maya tombs. In the Tomb of the Red Queen inside Temple XIII in Palenque, the remains of a noble woman and all the objects inside the sarcophagus were completely covered with bright red vermilion dust, made of ground cinnabar, perhaps intended to suggest blood, the symbol of life.

In China, the first documented use of cinnabar as a pigment was by the Yangshao culture (5000–4000 BC), where it was used to paint ceramics, to cover the walls and floors of rooms, and for ritual ceremonies. [19] The principal source of cinnabar for the ancient Romans was the Almaden mine in northwest Spain, which was worked by prisoners.
The levels of lead found in the six cinnamon products were elevated from what regulators expect, but lower than those that have been found in other products. Lead was found at concentrations ...
