The mineralogical composition of archaeological pottery provides important information about the origin and manufacturing technology of ceramic artifacts. Techniques such as X-ray diffraction, Fourier-transform infrared spectroscopy, and petrographic analysis are commonly used to determine the mineralogical phases. This study investigates the non-invasive analysis of the mineralogical composition of archaeological pottery using reflection FTIR spectroscopy.
The mineralogical composition of archaeological pottery is closely related to the raw material and the firing conditions, thus constituting a source of information both on the origin and the manufacturing technology of ceramic artefacts. The techniques used to clarify the composition of the ceramic material from the point of view of the mineralogical phases include X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR) and petrographic analysis. Such techniques normally require the taking of a sample from the object, thus often limiting their applicability to sherds rather than intact vessels. The present study aims to investigate the possibility of applying reflection FTIR spectroscopy in the mid- and near-IR to the non-invasive analysis of the mineralogical composition of archaeological pottery, with reference to a set of Etruscan ceramic materials from the excavation of Tarquinia (Italy).
