tar. The heavy, oily, darkcolored liquid called tar comes from wood, coal, bones, and other organic substances. It is made by the process called destructive distillation—subjecting the materials to intense heat in the absence of air. Coal tar is the source of some fabrics, many dyestuffs, and other useful products (see CoalTar Products ).

Coal gas was produced through the distillation of bituminous coal in heated, anaerobic vessels called retorts. In this process, coal was broken down into its volatile components through the action of heat in a nearly oxygen free environment. During the retorting phase, approximately twofifths of the coal's weight was converted into
