The techniques used to produce material culture objects represent fundamental aspects of intangible cultural heritage. While they rely on tangible tools and materials, their execution—how these elements intertwine with the artisan’s craft to create the final product—is inherently intangible. Traditionally, such techniques are passed down through generations via oral instruction and long-term practical apprenticeship. However, they leave little physical evidence in the resulting objects. The study of construction techniques in handmade (non-wheel-thrown) pottery is a key focus of archaeological and ethnographic research. Handmade pottery retains a wealth of manufacturing traces within its vessel walls, many of which can be effectively revealed using modern, non-invasive imaging techniques such as X-ray μ-CT. By enabling direct visual analysis of 2D virtual thin sections and 3D representations, μ-CT reveals the precise morphology of construction units (e.g., coils, slabs) and their joins, as well as the shape, size, orientation, and distribution of pores and non-plastic inclusions within the ceramic fabric. This paper presents the results of μ-CT scanning on a pottery assemblage from Middle Neolithic Sesklo (6th millennium BC), addressing three key aspects: 1. The potential of visual analysis, 2. The methodological implications of μ-CT for studying ancient ceramics, and 3. The contribution of μ-CT analysis to documenting intangible cultural heritage through material remains.
