“…[26] Actually, we noticed that cinnabar was employed in the red decorative layers of the sarcophagus of the Amazons, [33] in wall paintings of tombs in Paestum (as in the Tomb of the Diver; fifth-last 25th of the fourth century BC), [34] in Ruvo (tomb of dancers; end of the fifth-half of the fourth century BC), Arpi (tomb of the throne; end of the fourth century BC), [35] and in Taranto (via Umbria 162; the last 30 years of the fourth BC). [36] In this sense, we can speculate that the Lipari Painter could have conveyed of this lively artistic experience, bringing the employment of the pigment over the traditional use. Indeed, the relations between Lipára and the Tyrrhenian area were already dynamic at those times, as testified by the diffusion of other fictiles, [37] even if the trade of cinnabar for such artifacts remains an original data.…”

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.

“…Hand Held X-ray fluorescence devices (HH-XRF) and other portable XRF (pXRF) devices are regularly used in industry and are gradually being introduced also for archaeological/historical applications [1][2][3][4][5]. Within archaeometric research, previous studies have also employed pXRF devices in the measurement of the elemental composition of bulk and corrosion layers of copper-alloyed artefacts [1,4].…”

The study of archaeological artefacts using deployed in situ analytical instruments presents some obvious advantages. Including, obtaining an immediate feedback that can be used to redefine in real-time fieldwork strategies. Ideally analytical field instruments should also have characteristics that limit damage to the studied artefact.Here, we present a case study on the use of a Hand Held XRF (HH XRF) device employed to define the composition of copper-alloyed artefacts retrieved from the Roman military site of Fectio in the vicinity of Vechten (The Netherlands). The goals of the study were to establish artefact preservation status, to investigate artefact elemental composition, and to compare the composition of artefact corrosion layer and uncorroded core. The results showed that the objects were in an overall good preservation state. Decuprification and dezincification represented the probable main corrosion processes resulting in the formation of smooth corrosion layers or patinas. The major elemental composition of the artefacts' uncorroded cores showed a wide-range variability most likely associated with recycling practices of scrap metal during the 3 rd century CE.

“…The Cd-Te detection starts from Cl because of the low energy X-ray absorption in its thick window (4 µm), but the Cd-Te efficiency increases rapidly for higher energies improving its sensitivity. The detection limits [2] calculated as the ratio between the product of the concentration by three times the square root of the background and the peak area, for the Mo X-ray tube and for both detectors, show that the lower detection limits are reached in all the cases for the Si-PIN detector (Fig. 6).…”

“…X-ray fluorescence (XRF) is a fast and high sensitivity multielemental technique; it can be applied directly for non-destructive and non-invasive studies. [1,2] This technique is well established as a basic analytical tool for cultural heritage applications for more than 30 years. [3 -13] Although there are many museums and conservation laboratories equipped with static or portable XRF equipments in developed countries, nowadays, the use of portable devices for the characterization of objects and collections of museums, libraries, or in general, materials from the archaeological record or art history is fortunately increasing in countries of Latin America.…”

Destructive Analysis using X-rays) developed at the Physics Institute of the UNAM, Mexico, for the study of Mexican cultural heritage collections. The X-ray fluorescence (XRF) SANDRA device can use 75 W Mo, Rh and W X-ray tubes and Amptek Si-PIN and Cd-Te detectors that are selected and combined depending on the elemental range detection requirements and the specific problem to be studied. In this paper, a full description and characterization of this system, sensitivities for the X-ray tubes and detectors as well as the detection limits are discussed. Examples of applications to technological studies on pre-Columbian metallic artifacts and analysis of color materials of ancient Mexican codex are shown.
