Refined Coal, called fuel by some players, is used to power high-temperature industries, namely metalworking and glassworking. One unit of refined coal is required for every task at a smelter, metalsmith's forge, kiln, or glass furnace.
Refined coal is either charcoal, created by converting wood at the wood furnace, or coke, created by refining from bituminous coal or lignite at the smelter.
Also, refined coal is necessary in the production of steel and pig iron, even if using a magma smelter.
Charcoal
- Required Building - Wood furnace
- Required Material - Wood
- Required Skill - Wood burner
Charcoal can be created at a wood furnace using one wood log by a dwarf with the Wood Burning skill on.
Charcoal is stored on Bar/Block stockpiles.
Coke
- Required Building - Smelter
- Required Material - Bituminous coal or lignite
- (refined coal will be needed to power this at a normal smelter)
- Required Skill - Furnace operating
Coke is a type of refined coal used to fire non-magma furnaces. It is created at the smelter from bituminous coal, yielding 3 coke, and lignite, yielding 2.
Veins of lignite and bituminous coal will be ignited by magma, destroying the whole thing in a raging inferno.
