Cordage Analysis from Pottery

3D ModelNoAI

On the right side is shown a ceramic rim sherd with deep cordage impressions. On the left is a digital positive of the impressions showing the cordage that was impressed in the wet clay. From this digital positive we can determine that the cordage used to decorate it was manufactured with a final S-twist. Pottery with impressions such as these allow us to investigate perishable materials like cordage that do not normally survive in the archaeological record.
