Cinnabar Ore

"Cinnabar is a bright scarlet to brick-red form of mercury(II) sulfide, formula HgS. It is the most common source ore for refining elemental mercury, and is the historic source for the brilliant red or scarlet pigment termed vermilion and associated red mercury pigments. Cinnabar generally occurs as a vein-filling mineral associated with recent volcanic activity and alkaline hot springs."
