anthracite
n 1: a hard natural coal that burns slowly and gives intense
heat [synonym: {anthracite}, {anthracite coal}, {hard coal}]

Anthracite \An"thra*cite\, n. [L. anthracites a kind of
bloodstone; fr. Gr. ? like coals, fr. 'a`nqrax, ?, coal or
charcoal. Cf. {Anthrax}.]
A hard, compact variety of mineral coal, of high luster,
differing from bituminous coal in containing little or no
bitumen, in consequence of which it burns with a nearly non
luminous flame. The purer specimens consist almost wholly of
carbon. Also called glance coal and blind coal.
[1913 Webster]


Coal \Coal\ (k[=o]l), n. [AS. col; akin to D. kool, OHG. chol,
cholo, G. kohle, Icel. kol, pl., Sw. kol, Dan. kul; cf. Skr.
jval to burn. Cf. {Kiln}, {Collier}.]
1. A thoroughly charred, and extinguished or still ignited,
fragment from wood or other combustible substance;
charcoal.
[1913 Webster]

2. (Min.) A black, or brownish black, solid, combustible
substance, dug from beds or veins in the earth to be used
for fuel, and consisting, like charcoal, mainly of carbon,
but more compact, and often affording, when heated, a
large amount of volatile matter.
[1913 Webster]

Note: This word is often used adjectively, or as the first
part of self-explaining compounds; as, coal-black; coal
formation; coal scuttle; coal ship. etc.
[1913 Webster]

Note: In England the plural coals is used, for the broken
mineral coal burned in grates, etc.; as, to put coals
on the fire. In the United States the singular in a
collective sense is the customary usage; as, a hod of
coal.
