Initial compilation of a digital record of petrological thin-sections prepared from ceramics found in the United Kingdom, the English Heritage UKTS database, was completed in 1994. This paper was commissioned by English Heritage as one of a series of period studies designed to synthesise and review the contents of the database. From the total of c. 20,000 thin-sections recorded, c. 5500 (28%) relate to prehistoric pottery. Within the prehistoric entries, coverage varies both by period and by region. The main results are summarised by region, and a series of general discussion points is highlighted. The themes of technology, production, and exchange, the movement of pottery in the earlier prehistoric period, and the potential symbolic significance of inclusions such as rock, bone, and grog are all considered. Finally, recommendations for the minimum standardisation of petrological reports on prehistoric ceramics, and for further research, are outlined.
