    Abstract: Metallographic and metallurgical studies help to give insights into the history of technology of metal artefacts. Debris associated with pre-industrial metallurgical activity is found in piled up mounds at sites which are referred to as slag heaps. Slags refer to the waste or by-products from the process of extraction of metal from the ore by smelting which is a pyrometallurgical process of reduction of ore to metal in a heated furnace. Slags are typically partially vitrified or in a glassy state as a mixture of oxides and silicates with minor remnants of entrapped metal. The lighter viscous slag separates from the metal and is usually tapped out of the furnace, characterised as tap slag. Tuyeres refer to the blowpipes or nozzles used to generate a draught to work the furnace.
