Categories of coal

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 ....
