Summary Fingertip impressions preserved in the surface of clay artefacts can provide demographic details about the people who manufactured and decorated pottery vessels, and by extension allow exploration of the composition of communities of practice engaged in pottery manufacture. This paper describes the development of a method of measurement and analysis of fingertip impressions which were sometimes used as decorative motifs on pot surfaces. The technique can be applied to pottery from across archaeological periods; however, the research presented here focusses on communities of practice among Early and Middle Bronze Age potters of eastern England, and assessing their demographic make‐up through analysis of fingertip impressions. The preserved fingertip impressions reveal potting communities comprised children and women, but adult men were seemingly excluded, and suggest a connection between craft activity, age and sex.

Ancient fingerprints preserved in clay artefacts can provide demographic information about the people who handled and manufactured them, leaving their marks as an accidental record of a moment’s interaction with material culture. The information extracted from these ancient impressions can shed light on the composition of communities of practice engaged in pottery manufacture. A key component of the process is a comparator dataset of fingerprints reflecting as closely as possible the population being studied. This paper describes the creation of a bespoke reference collection of modern data, the establishment of an interpretive framework for prehistoric fingerprints, and its application to assemblages of Iron Age briquetage from coastal salterns in eastern England. The results demonstrate that briquetage manufacture was constrained by age and sex.
