“…[8] Among the different noninvasive methods, X-ray fluorescence (XRF) and Raman spectroscopy based on portable instruments have been demonstrated to be powerful techniques in the archeometric studies of artistic and archeological artifacts. [9][10][11][12][13][14][15][16] In this work, the color palette of a selection of vases currently exhibited at the Regional Museum in Lipára (Figure 1) has been characterized by portable XRF and portable Raman spectrometers, with the aim to complement and enrich our knowledge about the early Hellenistic Sicilian polychrome vase production.…”

One of the most impressive Sicilian pottery production is attributed to the socalled Lipari Painter and his followers, whose vessels-found in the archeological site of Lipari (Aeolian Island, Sicily)-are decorated with characteristic blue, red, and white figures. From the archeological point of view, these artworks keep open many questions concerning dating, production technique, and cultural background. In this context, new data on the manufacture procedures and on the raw materials used for the pigments may contribute to a deeper comprehension of this early Hellenistic vase tradition. The preciousness of the vessels, exhibited at the Archeological Museum of Lipari, imposed the use of in situ nondestructive methods to address new insights on the nature of the colored layers. Thus, analyses by Raman and X-ray fluorescence spectroscopy have been performed with portable instruments on a selection of vessels certainly attributed to Lipari Painter and to some others of his followers. The results of this study testify the use of different pigments: kaolin and gypsum, probably supplied locally, for white layers; Egyptian blue for blue hues; red ochre for brown-reddish hues; and cinnabar for pink and red-purple nuances. The identification of both Egyptian blue and cinnabar opens an interesting discussion about dating and circulation of the raw materials.

“…Hence, when an electron is ejected from an atom, consequently a photon (X-ray beam) is ejected. Therefore, each element produces specific fluorescent X-rays, a kind of fingerprint, that are unique for that specific component (Liritzis & Zacharias, 2011). The pXRF spectrometry is characterised by an external vacuum generator that enables identification of elements through surface analysis and avoids destructive analyses.…”

This paper discusses the use of non-destructive portable X-ray fluorescence (pXRF) to distinguish sources of variation in 8th Century BC Greek and Sicilian ceramics. The project comprises an element of my PhD study through La Trobe University, concerning Hellenic colonies established from the eighth century BC in the south of Italy, and on Sicily in particular. This specific case study looks at the relationships established between the indigenous site of Monte Finocchito and the Greek settlement of Heloros, both located in south-eastern Sicily. The results demonstrate the usefulness of the pXRF technique for detecting material variations which are not readily apparent using traditional visual analysis during fieldwork.

“…Modern machines can generate higher count rates, thereby improving counting statistics and reducing analytical time, by both increasing X-ray tube currents and by increasing detector efficiency and throughput (Frahm et al, 2014;Liritzis and Zacharias, 2011). Rather than trade in one pXRF instrument for another, our analysis indicated that we can decrease analytical time without sacrificing data quality by decreasing count time.…”
