Stones in coal, lots of clinkers - Solid Fuels: Coal, Coke ...

Sep 11, 2019· Coal, Coke, and Rocks. by Glenn Conner. Coal, to many people, is a black rock that sometimes can be burned. To a blacksmith, it is the fuel used in the forge to heat the metal, and comes in two varieties, good and bad. "Good coal" produces high heat, little ash, little clinkers (slag) and makes life so much easier.
