Distinction de céramiques glaçurées aghlabides ou fatimides (IX e-XI e siècles, Ifriqiya) par la mise en évidence de différences de texture au niveau de l'interface glaçure-terre cuite

In the area around Angkor, Cambodia, several ceramics kilns dating from the ninth to 15th centuries CE have been discovered since 1995. The technical, typological and compositional characterization of their production has been one of the main goals of the Cerangkor Project. Samples of green-glazed 'Kulen-type' stoneware and non-glazed stoneware produced in five kiln sites in the Angkor region were analysed chemically by wavelength-dispersive X-ray fluorescence spectrometry (WDS-XRF) and also petrographically. The data indicate that some workshops used similar raw materials for the same types of ceramics, suggesting the exploitation of the same geological formations in the whole region. Several references groups were established for each type of stoneware offering an important database for future provenance studies of sherds from consumption sites.

This article presents the typological and archaeometrical results obtained on the brown glazed stoneware of the Torp Chey kiln sites area. The ceramics were studied as part of the Cerangkor project, and several kiln sites were surveyed and analysed, including : Torp Chey, Veal Svay, Chong Samrong and Teuk Lek. More than sixty samples of brown glazed stoneware from the different kiln sites have been analysed chemically by XRF-WDS, twentyfive among them also petrographically. The data obtained indicate that the different kiln sites use similar raw materials suggesting the exploitation of the same geological formations for the whole area. Only one reference group has been therefore established, distinct from the productions of other Angkorian kiln sites and also from the productions of similar brown glazed stoneware from the Buriram sites (Thailand). Furthermore, the analysis of brown glazed stoneware obtained from consumption sites makes it possible to propose the first map showing the distribution of ceramics from production sites.

This paper presents the results of the provenience analysis of siliceous artefacts from Neolithic lakeshore settlements studied in the scope of the SNSF-project MET (“Mobilities, entanglements and transformations in Neolithic societies on the Swiss Plateau (3900-3500 BCE) supported by the Swiss National Science Foundation (Project No 100011 156205). The aim of this paper is to compare the cultural entanglements as defined by the pottery studies with the regions of origins of the knappable siliceous sedimentary rocks (KSSR) raw materials. The analysed siliceous artefacts were found in cultural layers of wetland settlements in the Northern Alpine Foreland, most of which are dated dendrochronologically with extreme precision. The sources of the raw materials were determined by the identification of the sedimentary microfacies of the siliceous artefacts, which allows the accurate location of the exploited outcrops without destroying the artefacts. This enabled detailed insights into complex entanglements, ties and mobility patterns in the raw material procurement between settlement communities on the Swiss Plateau, southern Germany and eastern France. Furthermore, these results were compared visually with stylistic entanglements in the pottery of the 4th millennium BCE. As a first attempt in this direction, this paper shows the potential of studies on mobility patterns when different find categories are studied in combination regarding their raw materials but also their typology.
