Though the fuel is now far less familiar a sight than it was a generation ago, coal is well known as a blackish rock hewn out of the depths of the earth or — if we are luckier — from near the surface. Rich in carbon, this rock is combustible. It is not a single mineral but a range of natural solids varying in composition. The complete range is broadly taken to extend from peat, through brown coal, lignite and bituminous coal to anthracite.
