Abstract

Some ceramics samples from Corvins Castle area - Coart Area, in different weathering stages, have been analyzed in this paper by different analytical techniques: XRD, thermal analysis (TG, DTG), porosity and thermoluminescence (TL) dating. For identification of the technology employed in the pottery production, the firing temperature could be determined through the presence of some minerals (evidenced by XRD), quartz and calcite being the most important ones. Crushed calcite is a good indicator, because it is present in the ceramics which have been tired up to 750° C (under oxidized atmosphere). By TL the nature of the crystalline network could be detected, ceramics consist of a number of crystalline inclusions (mainly quartz and feldspar) embedded in the ceramic matrix. The peak related to 343° C is always found in quartz. The date obtained by TL technique was in good agreement with the date assigned by archaeologists.
