Geochemical fingerprinting artefacts and sources has proven to be the most effective way to use material evidence in order to reconstruct raw material procurement practices, intra- and inter-community interactions, and mobility patterns among past societies. In order to facilitate access to this growing body of data and to promote comparability and reproducibility in provenance studies, we designed Pofatu, the first online and open-access database presenting geochemical compositions and contextual information for archaeological sources and artefacts.
