Non-invasive investigation on pigments of the Aeolian Islands Neolithic pottery
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…
Improved chemometric approach for XRF data treatment: application to the reverse glass paintings from the Lipari collection
The Aeolian cultural heritage preserves hundreds of testimonies of the past that have passed through six millennia of history. Among these, the Archeological Park of the Aeolian Islands with the Museum Luigi Bernab`o Brea (Italy) preserves a valuable set of artworks, which are related to a little-known ‘popular’ figurative heritage. It is an assemblage of small glass foils decorated using the technique of reverse painting, datable to between the end of the 17th century and the end of the 18th century, and actually under investigation by historians. Here, an X-ray fluorescence (XRF) spectroscopy study (performed with portable equipment) is combined with a multivariate approach that allows us…
