Element:COAL. Coal, Burns very slowly. Gets red when hot. Coal does not turn to instantly, like other flammable elements. When a coal particle is next to fire, its life value will start decreasing. Once it drops below 100, the coal will start releasing fire, and when its life is 0, it disappears. Coal starts with 110 life.
