Clinker (waste)

Clinker is a general name given to waste from industrial processes, particularly those that involve smelting metals, welding, burning fossil fuels and use of a blacksmith's forge, which commonly causes a large buildup of clinker around the tuyereClinker often forms a loose, dark deposit consisting of waste materials such as coke, coal, slag, charcoal, and grit.
