Clinker (waste)


Clinker (waste)

Clinker is a general name given to waste from industrial processes — particularly those that involve smelting metals, burning fossil fuels and using a blacksmith's forge which will usually result in a large buildup of clinker around the tuyère. Clinker often forms a loose, black deposit that can consist of coke, coal, slag, charcoal, grit, and other waste materials.

Clinker may be reused for paving footpaths. It is laid and rolled, and forms a hard path with a rough surface.

Clinker often has a glassy look to it. It is much heavier than coke.
