||In this thesis the added value of using μ-CT scans in the study of archaeological textiles is studied. To study the potential of this technique, two samples of the textiles from the sites of Oss-Vorstengraf and Uden-Slabroekse Heide were analysed. These Early Iron Age sites are among the few prehistoric sites that have brought forth preserved archaeological textiles. The sites were chosen because of their precise dating and their thoroughly documented context information. The textiles fragments of both sites have been mineralised through their contact with metal objects and thus have been mineralised.
For this research the two samples were scanned with μ-CT at a synchrotron facility. The μ-CT data was used to create 3D representations of the scanned textiles. The potential of μ-CT in the study of archaeological textiles was assessed by comparing the 3D representations of the textiles, with the results of the analysis with SEM, Scanning Electron Microscopy, and the results of the technical analysis of the same samples.
With the 3D representations of the textiles, it is possible to thoroughly study the structure of a textiles from all possible angles and it provides the ability to create cross-sections of the textile. To assess the preservation of the textile and the determine the source of the fibres, SEM is the most optimal technique to be used, since it provides the required view of the surface of the individual fibres, which is lost with the 3D representations. Still, when using μ-CT to study archaeological textiles, the costs and efforts to create the 3D representations should be taken into account.
In the future, the combination of μ-CT and SEM might prove to be a valuable combination to study archaeological textiles.
