For this study, microCT was applied to replicas of Minoan cups from Phaistos, Southern Crete, at the Multidisciplinary Laboratory of the Abdus Salam International Centre for Theoretical Physics, in Trieste.

These experimental replicas were produced by Cretan potter Vassiliki Politakis, in collaboration with Ilaria Caloi, following strict experimental procedures and using natural clays and tools from Minoan times. The potter’s wheel used was constructed based on models proposed by scholars of Minoan Crete. Four distinct ceramic techniques were employed: throwing-off-the-hump, wheel-throwing from a solid clay ball, wheel-pinching, and wheel-coiling.

The integration of microCT-derived information with traditional macroscopic observations has proven to be a powerful method for reconstructing the technological processes behind ancient pottery.

The study highlights several key findings, such as the identification of technological joints in cups produced using the wheel-coiling technique, differences in thickness variation between cups produced solely on the potter’s wheel and those combining hand-building techniques, and distinct void orientation patterns corresponding to different forming techniques.

Lead author Ilaria Caloi remarked, "This research represents a significant advancement in our understanding of ancient ceramic technologies. By combining traditional and advanced imaging techniques, we can more accurately reconstruct the methods used by ancient potters, highlighting their craftsmanship and technological capabilities."

Federico Bernardini added, "The integration of microCT in archaeological studies offers new possibilities for non-invasive analysis of cultural heritage artifacts. This approach preserves the integrity of the artifacts while enhancing our understanding of ancient manufacturing processes."

This pioneering research opens new avenues for studying ancient pottery and provides a model for future archaeological investigations. The findings not only enrich our knowledge of Minoan pottery but also demonstrate the potential of combining traditional and digital methods in archaeological research.
