Anthracite Anthracite Anthracite, often referred to as hard coal, is a hard, compact variety of coal that has a submetallic luster. It has the highest carbon content, the fewest impurities, and the highest energy density of all types of coal and is the highest ranking of coal. Anthracite is the most metamorphosed type of coal (but still represents low-grade metamorphism), in which the carbon content is between 92% 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
History of anthracite coal mining in Pennsylvania British navy blockades through during the war, industrialist Josiah White set his mill supervisors the task of experimenting with Anthracite to get to ignite and burn in a useful way. In 1813, the first mining actually in the Lehigh Valley was begun at Beaver Meadows, however, because of the various struggles getting it the to Philadelphia and because it is far more difficult to ignite Anthracite with its sporadic and unreliable supply did not come to be generally used regularly until after the War of 1812 and Hazard and White showed the way.
