AbstractThis paper offers an analysis of a group of glazed ceramics that comes from El Tolmo de Minateda site and have been dated in the second half of the ninth century and beginning of the tenth century, before the proclamation of the Umayyad Caliphate by Abderraman III (929 CE). Three technological groups have been distinguished: transparent glazes of one or two colours, transparent polychrome glazes (represented by two pieces) and opaque polychrome glazes (represented by two ceramics) studied by SEM-EDS analysis. After the study, different al-Andalus glaze workshops have been identified as providers of glazed ware to El Tolmo de Minateda site. The initial hypothesis was that the ware consumed in El Tolmo was manufactured in Pechina, the closest early production centre. However, after the archaeometric analysis, it has been discarded, and all the indications of this study seem to point to Córdoba as a significant supplier. The data of this study provides a new perspective on how the internal regional distribution and marketing of goods took place in Al-Andalus during the late Emiral period (c. 875–929 CE), a subject that has yet to be explored.
