Anthracite Carbon
Strong coal, also known as anthracite, is hard, compact coal with a submetallic lustre.
It is the highest rating of coals because it has the highest carbon content, the fewest impurities, and the highest energy density of all grades of coal.
Anthracite is the most metamorphosed coal (though it still reflects low-grade metamorphism), with a carbon content ranging from 86 to 98 percent.
The term refers to coal varieties that do not produce tarry or other hydrocarbon vapours when heated below their ignition stage.
Anthracite is difficult to ignite and produces a brief, blue, smokeless flame.
