A Complete Analysis of Cinnabar Producing Areas: Main Regions and Quality Characteristics Made Easy to Understand

Cinnabar, also known as cinnabarite or dansha, is a mineral whose main component is mercury sulfide. Since ancient times it has served both as a traditional Chinese medicinal material and as a red raw material for making seal paste and painting pigments. Its crystals are mostly bright red or dark red, with a vivid luster, and it has long been regarded as a rather precious mineral. It should be noted that although the garden plant Ardisia crenata (coral ardisia) has a similar name in Chinese, it has nothing to do with mineral cinnabar.

Cinnabar resources in China are mainly concentrated in the Guizhou and Hunan area, and the Wuling Mountains at the border of eastern Guizhou and western Hunan are especially well known. Among these, Wanshan in Guizhou is known as China's mercury capital because of its large reserves and long mining history. It is also produced in places such as Fenghuang and Xinhuang in Hunan, while abroad the deposits in Spain, Italy and other places are relatively famous.

Cinnabar from different producing areas differs in color, transparency and impurity content, and those with vivid red color, luster and fine texture are usually considered the best. Natural cinnabar often occurs together with rock, and after extraction it must undergo crushing, washing, water grinding and other processing steps before it can be made into the fine powder used for medicine or seal paste.

In terms of applications, cinnabar is traditionally used in Chinese medicine to calm the mind, mostly in pills and powders or for external use, but because it contains mercury, it must be used under a doctor's guidance and should not be taken on one's own for a long time. When buying cinnabar bracelets, ornaments and other accessories on the market, pay attention to distinguishing natural raw ore from synthetic products, and purchase through proper channels while checking the source information, so as to be better protected.
