Anthracite is a collection of Web mining power tools combined in an easy-to-use graphical environment that lets users quickly and seamlessly extract data from Internet sources, modify it to suit their needs, and export it to templates or databases, e.g. for RSS feeds.
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.
A hard, jet-black coal that develops from lignite and bituminous coal through metamorphism, has a carbon content of 92% to 98%, and contains little or no gas. Anthracite burns with an extremely hot, blue flame and very little smoke, but it is difficult to ignite and both difficult and dangerous to mine.
