Global debate about how to navigate the climate crisis often centers on high-level pledges and whether national targets are being met. Yet focusing on these technical outcomes obscures a deeper problem that keeps climate action falling short.
Ceramics are one of the most important sources of information for archaeologists. Yet how these objects are produced, especially in the firing stage, has received little attention to date. The excavation of a well-preserved pottery workshop at one of the most significant
