The Book of Abstracts of the 17th European Meeting on Ancient Ceramics (EMAC 2025), held at the Bizkaia Aretoa (University of the Basque Country, UPV/EHU) in Bilbao, Spain, 10–12 September 2025, compiles the full set of oral and poster contributions. EMAC is a long-standing biennial forum at the intersection of archaeology, archaeometry, materials science, and heritage conservation. This edition highlights non-destructive analytical approaches and presents advances across seven topics: raw material and provenance studies; experimental archaeology, ethnoarchaeometry and organic residue analyses; portable and non-destructive analyses; digital and data-driven ceramic studies; technology, production and dating; theory and methods; and preventive conservation and preservation strategies.
