This article is concerned with the technological characteristics of the pottery made according to traditional methods in the second millennium B.C. (Old Babylonian and Kassite periods), which was found at Tell ed-Der, Sippar, Isin, and Nippur. This pottery is not a highly sophisticated product; it has all the characteristics of fast-produced, standardized and wheelmade consumer ware of small and large vessels consisting of plates and bowls, cups, goblets and jars. It is in general undecorated and of a relatively uniform buff colour. We will try to present an idea of the work of Mesopotamian potters who made this ware, from digging, preparing and shaping the clay to firing the pottery. The technological analysis was carried out as part of the preparation of a Corpus of Mesopotamian Pottery by a number of archaeologists and the Department of Pottery Technology of the University of Leiden united in the Working Group on Mesopotamian Pottery. This pottery corpus should be a reference system of pottery shapes for dating and comparative purposes. It should also present the technological information and its relationship to the morphological data.
