Musawwarat es-Sufra - in search of ceramic raw materials

AbstractLaboratory analysis of pottery discovered at Musawwarat es-Sufra revealed the presence of wares made from wadi clays, hafir clays and alluvial clays. Searching for the source of the raw materials was carried out: 1) within the immediate vicinity of Musawwarat es-Sufra, aimed at obtaining samples of raw materials from various wadis (searching for ceramic raw materials used to produce local pottery, i.e. ceramics attributed to reference groups Mus 1–5); 2) within the immediate and wider vicinity of Musawwarat es-Sufra, aimed at finding raw materials from which samples identified as “probably local” could have been made (these are mostly handmade vessels made of various raw materials with lower levels of aluminium and a higher content of fluxes than samples attributed to groups Mus 1–5); 3) within the nile valley, aimed at sampling alluvial clays from various locations along the river (searching for ceramic raw materials used to produce local pottery attributed to Clay type A, i.e. ceramics made from nile alluvial clays). Collected raw material samples have been the subject of: plasticity test, firing test, chemical analysis, X-ray diffraction analysis. Additionally, laboratory model studies were performed to check what impact the chemical composition of organic tempers and so-called kaolinitic temper has on the chemical composition and thermal behaviour of ceramic sherds and the effect that adding various types of temper has on the mechanical and physical ceramic properties of sherds, and whether their use is attributable to a valid technological reason or simply to tradition.
