Variability in coiling technique in LBK pottery inferred by experiments and pore structure micro-tomography analysis

The article aims at identifying the origin of voids left by burnt-out organic material within the ceramic paste of Neolithic pottery from the Czech Republic territory. In methodological terms, an experimental reference collection was created and compared with the original early Neolithic pottery from the sites of Bylany by Kutna Hora and Tesetice-Kyjovice. The key analytical procedure consisted in non-destructive 3D micro-tomography (uCT) analysis, which is especially well suited for the study of the internal spatial organization of voids and temper. It allows to determine whether it is possible to define different manufacturing techniques employed for vessel construction on the basis of internal distribution of voids. The research identified cow dung as the probable organic temper within the original LBK ceramic paste. The 'S'-forming technique, consisting in pressing the coil to the vessel wall, most closely corresponded to features observed at the Neolithic vessels.
