Rice chaff in ceramics from the archaeological site of Sumhuram (Dhofar, Southern Oman)

The identification of the chaff used as temper in ancient ceramics represents a possible source of information about the area of origin of the pottery. This paper studies the occurrence of rice (Oryza sp.) chaff in potsherds from the archaeological site of Sumhuram (Dhofar, Sultanate of Oman). The information gathered at the site offers insight into commerce routes and networks to which the town belonged in the first centuries AD. The analysis of the plant material in the pottery and potsherds can also furnish interesting data on the ancient technologies of pottery production.
