The extensive excavations recently held at a potter’s workshop in Qalhāt on the Omani coast allowed us to follow the evolution of this ceramic production center between the end of the 13th century and the second half of the 14th century, and to bring to light three kilns among which two have a double chamber separated by a sole. These excavations have also provided useful insights into the medieval ceramic production in Oman, the technics involved and the vessels produced. The assemblage of local ceramics, glazed and unglazed, covers all domestic forms: jars, jugs, bottles, basins, bowls and oil lamps. The typo-chronological study of this material was carried out in order to highlight the evolution of the assemblage during the 14th century.
