The studied artifact is a stone bowl from the twelfth excavation season at Burnt City, Sistan, between 1997 and 2008, retrieved from trench NFB, burial 8509. Most stone artifacts in the past were made from gypsum alabaster or limestone marble, which are visually similar. Through sampling and thin-section petrography, the results revealed a layered limestone structure containing calcite and aragonite minerals, confirming the bowl’s marble composition. Regarding the manufacturing technology of marble artifacts, evidence of tool marks on the studied bowl suggests the use of tools such as hammers, chisels, drills, gouges, saws, and abrasives in the production of stone vessels.
