Lignite increases in maturity by becoming darker and harder and is then classified as subbituminous coal. After a continuous process of burial and alteration, chemical and physical changes occur until the coal is classified as bituminous dark and hard coal. Bituminous coal ignites easily and burns long with a relatively long flame. If improperly fired bituminous coal is characterized with excess smoke and soot.
