The Evolution of Pottery Production During The Late Neolithic Period at Sialk On The Kashan Plain, Central Plateau of Iran

The prehistoric sherds recovered from the North Mound of Tepe Sialk were investigated using XRF, XRD and SEM/EDX analyses. These studies showed the occurrence of a gradual evolution in pottery‐making from the Sialk I to Sialk II periods, eventually leading to the production of bulk red pottery at the final phase of Sialk II. The relative similarity of compositions, homogeneous microstructures and the presence of high‐temperature phases demonstrated a high degree of specialization in the selection of raw materials and control of the firing temperature and atmosphere among the potters of Sialk in the sixth millennium bc, peaking at the final phase of Sialk II.
