A highly volatile mixture of fluid hydrocarbons, obtained from petroleum, as also by the distillation of bituminous coal. It is used in making air gas, and in giving illuminating power to water gas. See Carburetor.

A yellowish white, translucent mineral, consisting of the carbonates of lime and soda, with water.

eans of heat or chemical process, as a steam boiler, gas retort, or vessel for generating carbonic acid gas, etc.

e of copper, called copper glance. Glance coal, anthracite; a mineral composed chiefly of carbon. -- Glance cobalt, cobaltite, or gray cobalt. -- Glance copper, c -- Glance wood, a hard wood grown in Cuba, and used for gauging instruments, carpenters' rules, etc. McElrath.

One of a class of carbohydrates having from three to nine atoms of carbon in the molecules and having the constitution either of an aldehyde alcohol or of a ketone alcohol. Most glycoses have hydrogen and oxygen present in the proportion to form water, while the number of carbon atoms is usually equal to the number of…

Native carbon in hexagonal crystals, also foliated or granular massive, of black color and metallic luster, and so soft as to leave a trace on paper. It is used for pencils (improperly called lead pencils), for crucibles, and as a lubricator, etc. Often called plumbago or black lead. Graphite battery (Elec.), a voltaic…

use obtained by the oxidation of graphite; -- usually called mellitic acid. -- Graphitic carbon, in iron or steel, that portion of the carbon which is present as graphite. Raymond.

vey of New Jersey, consisting in the additional carburizing of the face of a piece of low carbon steel by subjecting it to the action of carbon under long-continued pressure at a very high heat, and then to a violent chilling, as by a spray of cold water. This process gives an armor plate a thick surface of extreme har…

A white, semisolid, spermaceti-like hydrocarbon, C16H34, of the paraffin series, found dissolved as an important ingredient of kerosene, and so called because each molecule has sixteen atoms of carbon; -- called also hexadecane.

A hydrocarbon, C11H24, of the paraffin series; -- so called because it has eleven atoms of carbon in each molecule. Called also endecane, undecane.

e of a liver-brown color, sometimes used in medicine. It is formed by fusing sulphur with carbonates of the alkalies (esp. potassium), and consists essentially of alkaline sulphides. Called also hepar sulphuris (.

Any one of several isometric hydrocarbons, C7H16, of the paraffin series (nine are possible, four are known); -- so called because the molecule has seven carbon atoms. Specifically, a colorless liquid, found as a constituent of petroleum, in the tar oil of cannel coal, etc.
