Anthracite (Greek aνθρακίτης (anthrakítes), "coal-like," from άνθραξ (ánthrax), coal) is a hard, compact variety of mineral coal that has a high luster. It has the highest carbon count, the fewest impurities, and the highest calorific content of all types of coals, which also include bituminous coal and lignite.
Anthracite is the most metamorphosed type of coal (but still represents low-grade metamorphism), in which the carbon content is between 92.1% and 98%. The term is applied to those varieties of coal which do not give off tarry or other hydrocarbon vapours when heated below their point of ignition. Anthracite ignites with difficulty and burns with a short, blue, and smokeless flame.
