For several centuries (9th to 14th AD), Sgraffito-type pottery was widely distributed across a vast region, including Iran, the Caucasus, Anatolia, Eastern Europe, and Transoxiana. Based on the typological studies of Grube and Allen, this pottery tradition is classified into five main groups—Simple Sgraffito, Splashed Glazed Sgraffito, Champlevé/Garrus, Agh Kand, and Amol—each named after geographic locations in Iran where examples were first identified. Despite this established classification, our knowledge of the actual production contexts—workshops, kilns, tools, and technological processes—remained speculative, relying mainly on unverified accounts from antique dealers. No systematic archaeological investigations of production sites had previously been undertaken. These gaps raise significant research questions: How did Sgraffito pottery technology develop over a span of five centuries? Which styles represent earlier phases, and which embody the latest technical innovations? To address these questions, I initiated fieldwork in 2015 in the southern part of northwest Iran, a region historically rich in ceramic traditions. Surveys identified more than 20 sites containing substantial Sgraffito pottery remains. Among them, the site of Aghche Rish was selected for excavation, marking the first archaeological project in Iran devoted specifically to uncovering Sgraffito pottery production workshops. Excavations revealed a complex dating from the 9th to 14th centuries AD. Finds included multiple pottery kilns, extensive quantities of Garrus and Agh Kand wares , residential structures, workshop buildings, kiln-support tools such as bars and tripods, glass bracelets, 10th-century coins, tombs, and a historical cemetery. The presence of both domestic and industrial features provides valuable insight into the organization of pottery production and the daily lives of the craftspeople. This article first examines the workshop activities at Aghche Rish, offering rare archaeological evidence of Sgraffito production in Iran, and then presents a detailed typological analysis of the pottery assemblage, contributing to a deeper understanding of its technological and chronological development.
