The pottery known as Amul Ware represents one of the most distinctive ceramic traditions of northern Iran during the 3rd–6th centuries AH (9th–12th centuries CE), characterized by its unique body fabric, manufacturing quality, glazed surface treatment, and decorative techniques. This study aims to conduct a typological analysis and develop a systematic framework for the structural classification of Amul Ware ceramics produced between the 3rd and 6th centuries AH. The findings demonstrate that although the term Amul Ware has traditionally been associated with incised underglaze ceramics, this ceramic tradition exhibits considerable structural diversity. Based on the overlapping morphological and technological characteristics, the assemblage can be classified into several subgroups, including monochrome and splashed-glazed wares within the glazed ceramic category, as well as incised, applied-relief, and plain (undecorated) types represented in both glazed and unglazed subcategories. The evolutionary development of these types indicates that changes in vessel morphology, paste quality, glazing techniques, and decorative patterns correspond closely with technological innovations in ceramic production and the broader cultural and economic transformations of the medieval Islamic period. Furthermore, the presence of shared characteristics between Amul Ware and ceramics produced at major centers such as Gorgan, Sari, Rayy, and Nishapur suggests the existence of technological and artistic interactions, and possibly exchange networks, among these production centers. At the same time, several distinctive structural features confirm the independent identity of Amul Ware as a recognizable ceramic tradition.
