This article examines a frequently overlooked aspect of cuneiform writing in Egypt: the materiality and technology involved in the production of cuneiform tablets, with a particular focus on the process of tablet firing. It is argued that firing was an integral part of tablet production that required learning and practice by the Amarna scribes. The successful firing of tablets to temperatures around 800°C is attributed to the robust and longstanding tradition of tablet manufacture in Mesopotamia, Anatolia, northern Syria and Hazor. In contrast, the lower firing temperatures observed in tablets from Egypt, Alašiya and much of the Levant are associated with the production and firing of cuneiform tablets as a recent technological innovation that required thorough mastery.
