The red pigment vermilion is obtained by grinding natural cinnabar or synthetic mercuric sulfide. The red pigment vermilion is mostly obtained by reduction from cinnabar. "Vermilion" is a color that originates from the pigment found in the mineral cinnabar. Mercury occurs in deposits throughout the world mostly as cinnabar (mercuric sulfide). Cabochon adornments are sometimes made of cinnabar, agate, moonstone, or amber. Lacquer mixed with powdered cinnabar is used to produce the traditional red lacquerware from China. The reaction is also common with red ink, which may contain cinnabar (mercuric sulphide). Usage of "hinthapada" (), a vermilion dye made from cinnabar was regulated. Terminal incorruptibility was an ancient Chinese belief associated with jade, gold, and cinnabar. The pigment was originally made by grinding a powder of cinnabar (mercury sulfide). Crystals are found throughout much of the Alpine region such as cinnabar, amethyst, and quartz. The cinnabar deposits in Slovenia are a notable source of cinnabar pigments. Mercury has been smelted from cinnabar for thousands of years. Abandoned mercury mine processing sites often contain very hazardous waste piles of roasted cinnabar calcines. Many insects, such as cinnabar moth caterpillars, acquire toxic chemicals from their host plants.
