Peat Lignite Bitumen Anthracite
The four forms of coal are lignite, sub-bituminous, bituminous, and anthracite. These forms differ in their carbon content and energy value, with lignite being the lowest in carbon content and anthracite being the highest.
Anthracite coal is harder than lignite coal. Anthracite has a higher carbon content and is more dense and brittle compared to lignite, which is softer and more crumbly.

Lignite is cheaper and more abundant than anthracite, making it more accessible for fueling fires. Lignite also ignites at a lower temperature, making it easier to start fires with lignite than with anthracite, which requires higher temperatures for combustion.

Peat is decayed vegetation probably thousands of years old but which has not been converted to coal. Lignite is called brown coal, again vegetable matter that has not become true coal. Anthracite is a very pure form of coal much valued for steam engines.
