Carinated vase ca. 3000-2250 B.C. Iran This biconical pottery vessel has a sharp edge around its middle where the two halves of the vessel were joined. It also has an abrupt shoulder and a wide, flaring rim. It is made of grey clay using a potters wheel, and decorated with several horizontal registers of hatching.This vessel was excavated at Yarim Tepe in northeastern Iran, six miles south of the modern town of Gonbad-e Kavus. Yarim Tepe was a small settlement, inhabited from the Neolithic to the Parthian period, with many interruptions. Very similar vessels have been excavated at Tureng Tepe near modern Gorgan, about 50 miles to the southwest, dating to the Bronze Age. This vessel likely dates to the same period. The similarity shows that these sites were in close contact with one another, perhaps as part of the trade network that linked Mesopotamia with Afghanistan, one of the few sources of tin and lapis lazuli in the ancient Near East..
