Anthracite (glance, blind-coal, stone coal or parrot-coal) is a kind of non-bituminous coal of a shining lustre, approaching to metallic, distinguished by its great hardness, its high proportion of carbon, and the great heat given out in burning without smoke, with a weak or no flame. It is sometimes called parrot-coal on account of the crackling or chattering noise it makes when burnt.
Anthracite is found in England, Scotland, and Ireland, and in large quantities in the United States, chiefly in Pennsylvania. Research Anthracite
