Steel made directly from cast iron, by burning out a portion of the carbon and other impurities that the latter contains, through the agency of a blast of air which is forced through the molten metal; -- so called from Sir Henry Bessemer, an English engineer, the inventor of the process.

Containing two atoms or equivalents of carbon in the molecule. [Obs. or R.]

A pale blue pigment, prepared from the native blue carbonate of copper, or from smalt; -- called also blue bice. Green bice is prepared from the blue, by adding yellow orpiment, or by grinding down the green carbonate of copper. Cooley. Brande & C.

Hydrous carbonate of bismuth, an earthy mineral of a dull white or yellowish color. [Written also bismuthite.]

By extension, any one of the natural hydrocarbons, including the hard, solid, brittle varieties called asphalt, the semisolid maltha and mineral tars, the oily petroleums, and even the light, volatile naphthas.

An earthy carbonate of iron containing considerable carbonaceous matter; -- valuable as an iron ore.

calcified tissue of the skeleton of vertebrate animals, consisting very largely of calcic carbonate, calcic phosphate, and gelatine; as, blood and bone.

A thin bed of coal mixed with pyrites or carbonate of lime.

ration, air which, in the process of respiration, has parted with oxygen and has received carbonic acid, aqueous vapor, warmth, etc. Melted as breath into the wind. Shak.

A carbonate of baryta and lime, intermediate between witherite and strontianite; -- called also alstonite.

An oxychloride of copper, used as a green pigment; also, a carbonate of copper similarly employed.

A zinc-carbon cell in which the zinc (amalgamated) is surrounded by dilute sulphuric acid, and the carbon by nitric acid or a chromic acid mixture, the two plates being separated by a porous cup.

gent, with evolution of heat; to consume; to oxidize; as, a man burns a certain amount of carbon at each respiration; to burn iron in oxygen. To burn, To burn together, as two surfaces of metal (Engin.), to fuse and unite them by pouring over them a quantity of the same metal in a liquid state. -- To burn a bowl (Game…

An inflammable gaseous hydrocarbon, C4H10, of the marsh gas, or paraffin, series.

Any one of three metameric hydrocarbons, C4H8, of the ethylene series. They are gaseous or easily liquefiable.

Partaking of the nature ofcalcite or calcium carbonate; consisting of, or containg, calcium carbonate or carbonate of lime. Clcareous spar. See as Calcite.

Bearing producing, or containing calcite, or carbonate of lime. Calciferouse epoch (Geol.), and epoch in the American lower Silurian system, immediately succeeding the Cambrian period. The name alludes to the peculiar mixture of calcareous and siliceous characteristics in many of the beds. See the Diagram under Grology…

it friable by the action of heat, esp. by the expulsion of some volatile matter, as when carbonic and acid is expelled from carbonate of calcium in the burning of limestone in order to make lime.

friable state, by the action of heat; to expel volatile matter from by means of heat, as carbonic acid from limestone, and thus (usually) to produce disintegration; as to, calcine bones.
