| This article is about an older version of DF. |
One of the two mineral sources of fuel, bituminous coal is found in veins in sedimentary layers. When processed at a smelter or magma smelter, one unit of bituminous coal produces 3 units of coke. If done at a regular smelter, this processing requires one pre-existing unit of fuel (either charcoal or coke), leaving a net production of 2 fuel.
Bituminous coal is flammable. (It should not be necessary to add that it is not a fire-safe material.)
Bituminous coal is not the same as "refined coal", "coal fuel", or "coal", though it is directly related.
