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. The previous edition of this document was compiled in 2001 by Justine Bayley, David Dungworth and Sarah Paynter with the assistance of the Historical Metallurgy Society's Archaeology Committee, with contributions by Peter Crew, Vanessa Fell, Brian Gilmour, Gerry McDonnell, Cath Mortimer, Peter Northover, David Starley and Tim Young. This edition was revised in 2015 by David Dungworth.
