The creation of a Roman colony at Corinth represented a turning point in various aspects of daily life, including the negotiation of collective identities through aesthetic tastes and fashions, consumption choices, and technological practices. This paper investigates continuities, changes, and knowledge transfer in the production of fine glazed pottery between the 2nd century BC and the 1st century AD. We investigate black-glazed mouldmade bowls of Hellenistic tradition (2nd–1st century BC) and lead-glazed tableware that are believed to reflect a Roman tradition (1st century BC–1st century AD). The study combines a petrographic analysis of the pottery fabrics, aiming to explore the regional provenance of the wares and clay exploitation strategies, and a SEM-EDS analysis of the waterproof glazes (with comparisons to Attic productions), aiming to assess the quality of the glazing materials and technology through time.Two major events, i.e. the destruction of the most part of the city center by the Roman general Mummius in 146 BC, and the re-foundation of the city as a Roman colony under Cesar in 44BC, appear as influential factors on the organization of mouldmade pottery craftsmanship in the city’s territory, with clay extraction strategies, decoration styles and techniques, and possibly workshop location being reorganized regionally throughout the mid-2nd and the mid-1st century BC. Early types of “Megarian” bowls include specimens with floral, figured, and imbricate decoration that all predate the mid-2nd century BC. Most of them are in an orange micaceous fabric, a few others in a greenish fabric; they may all originate from the immediate vicinity of the city center. The quality of their glaze is uneven, with the former products displaying shades of dark and red, and others a very worn black glaze. Other types of “Megarian” bowls with net-pattern, long-petal, and linear-leaf decoration are deemed to date from around the time of the destruction of the city by Mummius, or even later. Their styles are reminiscent of a contemporary Attic production, although the glaze is of medium quality. They appear in the same fabrics as early Roman lead-glazed pottery, and they relate petrographically to the wider region of Corinth.< Leer menos
