The earliest pottery vessels in the Arabian Gulf, appearing in the mid-sixth millennium BC, belong to two distinct traditions: Ubaid Ware was imported from Mesopotamia, but the origins of the Coarse Red Ware have remained obscure. Geochemical examination of pottery from Bahra 1, in modern-day Kuwait, and geological samples from the surrounding area reveal a regional origin for the clay. Further exploration of the Bahra 1 assemblage indicates that Coarse Red Ware was probably made at the site by low-skilled potters. This research provides insights into the organisation of pottery production and distribution in the Arabian Neolithic.
