The colours of Segesta. Searching for the traces of the lost pigments
2023
Many monuments and objects of the ancient civilizations were painted, but unfortunately the pigments are not still present and sometimes only small traces are evident. The analysis of the traces requires a multianalytical approach through the use of non-invasive techniques and only if necessary of a microsampling. Here, the study of the traces of colours found in some architectural elements and findings belonging to the Archeological Park of Segesta (Trapani, Italy) is reported. The traces are identified and characterised via several techniques such as Optical Microscopy, UV-Fluorescence Imaging, Fiber Optical Reflectance Spectroscopy (FORS), X-ray Fluorescence (XRF) and FT-IR Spectroscopy.…
Non-invasive investigation on pigments of the Aeolian Islands Neolithic pottery
2023
The Neolithic painted pottery, spread all over southern Italy, is considered as an important chronological indicator for the development of VI-V millennium BC prehistoric settlements and cultural traditions. The goal of this work is to contribute to the study of this ceramic class through the chemical characterization of some samples coming from the Aeolian Islands. 16 different sherds have been selected and the pigments preserved in their decorations analyzed via non-invasive techniques: Fiber Optical Reflectance Spectroscopy (FORS), X-ray Fluorescence (XRF), Raman Spectroscopy and Infrared Spectroscopy (FT-IR). The different pigments, some of which no longer clearly visible to the naked e…
