“…The authors gave the list of commonly used pigments together with their chemical composition and depth penetration of X-rays for selected pigments useful for X-ray spectra interpretation and age estimation. The necessary data for EDXRF analysis of multilayers (Renaissance paintings on canvas or wood) can be also recorded from visible reflectance spectroscopy [60,61]. FP method can be also used for EDXRF analysis of modern and ancient papers [62,63].…”

In the field of cultural heritage analyses, energy dispersive X-ray fluorescence is a well known nondestructive technique used -among other applications -to characterize pigments and inks in artifacts such as paintings, polychromous sculptures and illuminated manuscripts. In this paper, we report on the performance of three portable X-ray fluorescence analyzers currently used for laboratory or in situ analyses. The three spectrometers have been tested in laboratory on paint layers prepared to simulate real ones, with the specific goal to determine advantages and disadvantages for each instrument in the detection of specific elements characterizing the pigment. Additionally, overall general advantages and limitations of each system in practical use are highlighted.

“…This type of instrument is routinely used in analysis of several archaeomaterial types-for example, pottery (Bonizzoni, Galli & Milazzo, 2010), bronzes (Bonizzoni, Galli & Poldi, 2008), wood (Franceschi, Cascone & Nole, 2008) and paintings (Bonizzoni, Galli, Poldi & Milazzo, 2007).…”

Abstract:In the study of archaeological ceramics, it is important to have compositional data to identify their origin and source. The fabric also provides useful information on the production technology, especially with regard to the firing steps. The work presented here is connected to this field and focuses on the main parameters related to the terracotta artefacts preparation. Thus, one can consider the effects in terracotta characteristics of different raw materials and firing parameters, in particular for pottery of Caltagirone, which is one of most important centres of pottery production in Italy, active since the Neolithic. To this end, terracotta samples have been reproduced in a laboratory setting according to the ancient procedure of Caltagirone manufacture, starting from clay and degreaser extraction in local historical sites. The analysis was conducted using a portable X-Ray Fluorescence (pXRF) spectrometer for elemental characterization of sand degreaser and of clays during each step of the realization process and in different firing conditions. SEM-ED techniques were also employed to verify the method and results for some of the samples after firing process. Framing the technological context of manufacture production, known in the specific case, it is also possible to identify potential outcomes and limits in the study of potsherds using pXRF technology, in applying the methodology to historic artefacts.
