Cinnabar is a crystal with a long and varied history of use. It was once thought to be the philosophers' stone, and it has been used for everything from spiritual healing to protection against negative energy. Today, Cinnabar is still prized for its many benefits, including its ability to promote physical health, mental clarity, and spiritual awareness.
Cinnabar, the most common ore of oxidized mercury found in nature, occurs in granular crusts or veins associated with volcanic activity and hot springs. The ruddy hue of this natural mineral pigment embodies the hot and fiery conditions in which it forms. From left to right: Cinnabar crystal; volcanic eruption; powdered vermilion.
Cinnabar color ranges from bright red to purplish or brownish hues. Cinnabar was widely used as the source of pigment vermillion. Cinnabar is transparent to opaque with an adamantine to dull luster. Cinnabar's hardness is rated 2 to 2.5 on the Moh's scale of mineral hardness. Cinnabar is found in China, Peru, Italy, Spain, and in the U.S.A ...

Because cinnabar rock has such a high mercury content, it has often been used to provide mercury to thermometers, emergency sprinklers, and light bulbs. Of course, cinnabar has also been used for jewelry and pigment production. Controversially, cinnabar is still used in traditional Chinese medicine. What is Cinnabar Jewelry
Like other metals, mercury is extracted from ores - one of the main varieties being cinnabar. It is found mostly in China, Spain and California. Droplets of liquid mercury can actually be found within the ore, though it is usually extracted through heating.
It is obtained naturally by grinding ore into a fine powder then mixing the powder into dyes, paints and other finishes such as lacquer. It can also be manufactured by treating a mixture of liquid mercury and sulfur with potassium hydroxide. Cinnabar is the primary pigment in colors commonly referred to as vermillion and Chinese red.
Cinnabar is a mercury sulfide mineral with the chemical formula HgS. It is a vibrant red color and is an important ore of mercury. It is primarily found as fillings within gaps of rocks and coating rocks as a result of ascending hydrothermal activity. While cinnabar is typically massive in habit, large crystals have been found on rare occasions ...
Prolonged contact with various forms of mercury has caused physical and mental debilitation and even death among cinnabar miners, gold miners, and industrial …

A rarer form of cinnabar appears as striking deep red crystals embedded in other rocks. How do we get the mercury out? Cinnabar is crushed into small pieces and heated in a kiln. When the temperature hits 675 degrees Fahrenheit, the liquid mercury becomes a vapor. As that vapor cools, the mercury condenses into a pure liquid that …
Cinnabar, or mercury sulphide (HgS), is a highly toxic, naturally occurring form of the mercury mineral, which was used in the ancient past for producing a bright …
The cinnabar ore used during this period was obtained from Almadén, Spain, the largest mercury mine in the world. As a pigment, cinnabar possesses many …
A new hydrometallurgical process is presented for obtaining mercury from cinnabar concentrates. The process consists basically of three successive stages. Cinnabar is leached with hydrochloric acid- potassium iodide solution, and the HzS generated in the reaction is removed from the reaction vessel ... assumed in the application of Eq. [1 ...
cinnabar, mercury sulfide (HgS), the chief ore mineral of mercury. It is commonly encountered with pyrite, marcasite, and stibnite in veins near recent volcanic rocks and in hot-springs deposits. The most important deposit is at Almadén, Spain, where it has been mined for 2,000 years. Other deposits are in Huancavelica, Peru; Iudrio, Italy; …
The red powdery form of mercuric sulphide, cinnabar, was definitely used by early Mesoamerican people, among other things, covering carved jade and ceramics. Pieces of cinnabar have been reported from the Highland Mexican site Chalcatzingo, dating before 900 BC, when a burial at the site contained a green serpentine figure so …

Cinnabar, also known as Cinnabarite, is a mercury sulfide mineral that usually crystallizes in the form of masses, but has been seen in the shape of tabular and rhombohedral crystals on a matrix.
Mercury - A Tale of Two Toxins Gary Bigham, Betsy Henry, and Brad Bessinger is one of the most unusual of the regu-lated environmental contaminants, with a complex chemistry and rich history. It can assume a variety of chemical forms including liquid elemental mercury and solid cinnabar in mineral deposits, gaseous elemental mercury in air, and ...
In cinnabar's natural mineral and pigmented form, it's not dangerous. However, when temperatures rise, it releases a mercury vapor which can be toxic if inhaled. "Mercury is toxic, but as long as the cinnabar isn't heated, the mercury is locked by the sulfur, making cinnabar low in toxicity," Ottaway explains.
However, cinnabar is actually the name of a red mineral, a form of mercury (II) sulfide, used to dye the lacquer. While most cinnabar objects are a deep scarlet hue, other lacquer colors can be achieved with different minerals, such …
