This guidance document provides an introduction to the ways that the archaeological evidence for metalworking is studied. Archaeometallurgical evidence can include whole landscapes, buildings, features, artefacts and waste materials (eg slag and crucibles). Archaeometallurgy includes fieldwork investigations (survey and excavation) and the subsequent study of these data as well as any artefacts and residues recovered. Scientific approaches provide insights into the techniques used to produce different metals and how these were fabricated into artefacts.
