MINERO‐PETROGRAPHIC STUDY OF COOKING WARE AND POMPEIAN RED WARE (ROSSO POMPEIANO) FROM CUMA (SOUTHERN ITALY)

Excavations carried out in Cuma by the Centre Jean Bérard archaeologists have uncovered a large quantity of pottery. This study is focused on cooking ware and on internal red‐slip cookware, also known as Pompeian Red Ware (Rosso Pompeiano), dated from the first century bc to the first century ad . A comparison with the minero‐petrographic composition of beach sands collected along the Bay of Naples coastline highlights the provenance of the temper from the Somma‐Vesuvius area, marked by leucite‐bearing scoriae and garnet. Petrochemical analyses allow us to distinguish two main groups of pottery characterized by different technological options based on the amount of temper and on the type of clay. X‐ray diffraction and scanning electron microscope data demonstrate improved accuracy in the production of Rosso Pompeiano, especially with regard to firing control, which was in a prevailing oxidizing atmosphere and in a narrow thermal range, between about 800 and 900°C.     

BYZANTINE CERAMIC PRODUCTION FROM CUMA (CAMPI FLEGREI,NAPOLI)*

Samples of table and cooking ware, dating back to the Byzantine period of the ancient Greek colony of Cuma, were analysed by optical microscopy, X‐ray diffraction, X‐ray fluorescence and scanning electron microscopy, in order to reconstruct the main technological properties of these manufactures. The comparison of minero‐petrographical data from these samples with those of some kiln wastes allowed us to hypothesize a local manufacture for most of the investigated specimens and to confirm the relative reference groups. A restricted number of samples did not link with the main groups, indicating a regional (or maybe extra‐regional) production, in agreement with the widespread circulation of this high‐medieval ceramic production in southern Italy.
