ETYM Perh. akin to cake, n .
Produced by distillation of coal. Clean, light fuel produced when coal is strongly heated in an airtight oven. Coke contains 90% carbon and makes a useful domestic and industrial fuel (used, for example in the iron and steel industries and in the production of town gas).
The process was patented in England 1622, but it was only in 1709 that Abraham Darby devised a commercial method of production.
