A carbonaceous material obtained by burning wood or other organic matter in the absence of air; SYN. wood coal.
A drawing made with charcoal.
A stick of black carbon material used for drawing; SYN. fusain.
A very dark gray color; SYN. charcoal gray, charcoal grey, oxford gray, oxford grey.
Black, porous form of carbon, produced by heating wood or other organic materials in the absence of air. It is used as a fuel in the smelting of metals such as copper and zinc, and by artists for making black line drawings. Activated charcoal has been powdered and dried so that it presents a much increased surface area for adsorption; it is used for filtering and purifying liquids and gases—for example, in drinking-water filters and gas masks.
Charcoal was traditionally produced by burning dried wood in a kiln, a process lasting several days. The kiln was either a simple hole in the ground, or an earth-covered mound. Today kilns are of brick or iron, both of which allow the waste gases to be collected and used. Charcoal had many uses in earlier centuries. Because of the high temperature at which it burns (2,012şF/1,100şC), it was used in furnaces and blast furnaces before the development of coke. It was also used in an industrial process for obtaining ethanoic acid (acetic acid), in producing wood tar and wood pitch, and (when produced from alder or willow trees) as a component of gunpowder.

ETYM Perh. akin to cake, n .
Produced by distillation of coal. Clean, light fuel produced when coal is strongly heated in an airtight oven. Coke contains 9carbon and makes a useful domestic and industrial fuel (used, for example in the iron and steel industries and in the production of town gas).
The process was patented in England 162but it was only in 17that Abraham Darby devised a commercial method of production.

ETYM AS. col; akin to Dutch kool, Old High Germ. chol, cholo, German kohle, Icel. kol, pl., Swed. kol, Dan. kul; cf. Skr. jval to burn. Related to Kiln, Collier.
(Homonym: cole).
Carbonized vegetable matter deposited in the carboniferous period; the material is combustible and has been used for heating since the mid nineteenth century.
Black or blackish mineral substance formed from the compaction of ancient plant matter in tropical swamp conditions. It is used as a fuel and in the chemical industry. Coal is classified according to the proportion of carbon it contains. The main types are anthracite (shiny, with about 9carbon), bituminous coal (shiny and dull patches, about 7carbon), and lignite (woody, grading into peat, about 5carbon). Coal burning is one of the main causes of acid rain.
In the second half of the 18th century, coal became the basis of the Industrial Revolution. Coal fields are widely distributed throughout the temperate N hemisphere, the greatest reserves being in Europe, W Siberia, and the US. In the Southern hemisphere, Australia is a major producer. An increasing use, from 1950–7of cheap natural gas and oil as fuel and for the production of electricity halted when the energy crisis of the 197led to greater exploitation of coal resources. Coal is becoming a major source of synfuel (synthetic gasoline). In the Fischer–Tropsch process (used in Germany in World War II and today in South Africa), the coal is gasified and then catalysts are used to reconstitute it into diesel and jet fuel. In the degradation process (under development in the US for high-octane motor fuel), a liquid fuel is directly produced by adding hydrogen or removing carbon from the coal.
