Coke is a manmade fuel, consisting of almost pure carbon.[1]
Traditional feed stocks for coke have been coal or petroleum. The feed stock is heated in air-tight containers, to separate the carbon from the volatile elements.
Coke burns very hot, and its flame does not introduce any other impurities into the product being heated than carbon.[2] In working with iron and steel, introducing carbon is a desirable side effect, as when case hardening.
Formerly gas driven off coal, during the production of coke was used to illuminate homes and offices.[2]
