摘要

This paper analyses a metalworking area from the fortified site of A Cidá de Borneiro (Cabana de Bergantiños, Galicia, Spain). It is focused on a bronze and iron workshop (C9-12) where, in addition to abundant metallurgical evidence and production remains, a large number of thermally altered bone fragments have been documented. The present work proposes a multifactorial analysis to understand together these bones within the context of metalworking activities. For this purpose, an archaeological and functional analysis of the workshop is combined with a morphological study of the bone remains. First, a contextual analysis is defined, examining the archaeological evidence in order to define what kind of activities were developed in the area. Concurrently, a macroscopic analysis of the characteristics and conditions of the bones is carried out, with the aim of identifying thermal alteration processes. As will be demonstrated, this research will confirm that the bones were used as part of the operational production sequence, particularly during the hardening process of objects that require a strong and sharp edge. Finally, we will define and examine the characteristics of this technique from a point of view that encompasses both the technical and symbolic dimensions of metalworking.
