What do you use cinnabar ore for

Mercury was used to shape the hats, exposing their makers to the substance. As a direct result of her undergraduate majors, she has an unhealthy interest in old rocks and natural hazards.

She has a blog on those subjects at www. I came across an article about cinnabar containing mercury. It gets a bit of sunlight and I am worried about mercury vapors in my home. Should I do anything else? I am I just being paranoid. How hot does the stone have to get to release mercury vapor?

Please email me at mepatrice yahoo. Your first sentence imealietmdy got me interested in this topic. Your unique commentary and writing style had me convinced of your points. Amazing work.

Please continue this type of content. Thank you,Mary, for your interesting discussion. I am interested to know how ancients first may have discovered cinnabar and its properties and about the ways in which mercury was used in early societies. Your email address will not be published.

Karson says:. December 27, at pm. Koby says:. The two minerals should not be confused with one another because metacinnabar has a metallic gray color, a gray-to-black streak and a metallic-to-submetallic luster. Chinese red cinnabar lacquer box: A carved wooden box with a red lacquer finish from China's Ming Dynasty Period box c.

Boxes like this were frequently painted with a lacquer containing a cinnabar pigment. Mercury still: Textbook sketch of a still used for the distillation of mercury from cinnabar. Public domain image from Alchimia, Anonymous, Cinnabar is the only important ore of mercury. For thousands of years, cinnabar has been mined and heated in a furnace.

The mercury escapes as a vapor that can be condensed into liquid mercury. Through time, people in almost every country where volcanoes are present discovered cinnabar and realized its utility as a pigment. Cinnabar is one of a very small number of minerals that was independently discovered, processed and utilized by ancient people in many parts of the world. Cinnabar was mined at the volcano, ground into a very fine powder, and then mixed with liquids to produce many types of paint.

The bright red pigments known as "vermilion" and "Chinese red" were originally made from cinnabar. Cinnabar has been especially popular for making red lacquer in China. Its use in lacquer has declined because of its toxicity, but some use of cinnabar in lacquer continues.

Cinnabar has also been used in powdered form for ritual blessings and burials. Powdered cinnabar was used as a cosmetic in many parts of the world for thousands of years. Eventually it was discovered that cinnabar is toxic, and its use in pigments, paints, and cosmetics began to decline.

Today most, but not all, items made and sold under the name "cinnabar" have been made with less toxic and nontoxic imitation materials. Antique items made with toxic mineral cinnabar are still found in the marketplace. If you encounter an item for sale that is described or labeled as "cinnabar" you should be skeptical. If it is real cinnabar, it could be hazardous. If it is imitation cinnabar, if should be labeled as "imitation".

Mercury switch: Mercury has the ability to conduct electricity and flow under the influence of gravity. This switch is currently in the "off" position, but if it is moved so that the mercury runs to the right, surrounding the two wires, the circuit will be connected and the switch will be in the "on" position.

The best way to learn about minerals is to study with a collection of small specimens that you can handle, examine, and observe their properties.

Inexpensive mineral collections are available in the Geology. Because cinnabar is the only important ore of mercury, the demand for mercury has driven mining activity. Mercury has many uses, but its toxicity has reduced its use in any application where reasonable substitutes can be found. Large amounts of mercury are currently used in the chemical industry in the production of chlorine and caustic soda during the electrolysis of brine.

Mercury was widely used in temperature- and pressure-measuring instruments such as thermometers and barometers. It was often used in gravity switches because it flowed easily as a liquid and conducted electricity.

Most of these uses have been discontinued. Mercury is currently used in some batteries and light bulbs, but their disposal is often regulated. Because it is toxic, it was once widely used to protect seed corn from fungus and to deworm materials used to make felt.

It was used in dental amalgam but is being replaced by polymer resins and other materials. In almost all of its use, mercury is being replaced with less toxic and nontoxic substitutes.

Mercury has been widely used in mining to separate gold and silver from ores and stream sediments. Large amounts of mercury were spilled during these operations, and today, mercury used in the s is still being recovered from streams.
