Roman coins at the edge of the Negev: characterisation of copper alloy artefact...
Peters, M; Goren, Y; Fabian, P; Bottaini, C; Grassini, S; Angelini, E; Mirao, jThe research presented in this paper focused on the preliminary non- and semi-destructive analysis of copper alloys, corrosion, and soil components from a Roman archaeological site in Israel. Investigations using portable X-ray fluorescence, X-ray diffraction and scanning electron microscopy with energy dispersive spectroscopy as well as micromorphological analyses were carried out to gain a better understandin...
Islamic copper-based metal artefacts from the Garb al-Andalus. A multidisciplin...
Bottaini, C; Gómez Martínez, S; Bordalo, R; Beltrame, M; Mirão, J; Rafael, L; Schiavon, NA multidisciplinary approach has been applied to investigate the production technology of a collection of copper-based artefacts found during archaeological excavation campaigns carried out in the Almohad neighbourhood of Mārtulah, the Islamic name of modern Mértola (South of Portugal). In stark contrast to other Islamic materials found in the same site such as common and finely decorated pottery, glass, and bo...
Use of Monte Carlo Simulation as a Tool for the Nondestructive Energy Dispersiv...
Bottaini, C; Brunetti, A; Montero-Ruiz, I; Valera, A; Candeias, A; Mirao, JThis work is part of a broader research line that aims to develop and implement a nondestructive methodology for the chemical characterization of archaeological metals based on a protocol that combines energy dispersive X-ray fluorescence spectrometry (ED-XRF) with a Monte Carlo (MC) simulation algorithm. In this paper, the ED-XRF-MC protocol has been applied to estimate the chemical composition of a selected g...
Archaeometric contribution to the interpretation of the Late Bronze Age "hoard"...
Bottaini, C; Vilaça, R; Montero-Ruiz, I; Mirao, J; Candeias, AThis paper presents and discusses the results of the multi-analytical study carried out on a group of 39 Late Bronze Age artefacts from the site of Porto do Concelho, Central Portugal. The chemical composition of the objects was determined by Energy Dispersive X-ray Fluorescence (EDXRF) and their microstructural features were identified by Optical Microscopy (OM) and Scanning Electron Microscopy with Energy Dis...
New insights on Late Bronze Age Cu-metallurgy from Coles de Samuel hoard (Centr...
Bottaini, C; Vilaça, R; Schiavon, N; Mirão, J; Candeias, A; Bordalo, R; Paternoster, G; Montero-Ruiz, IThe hoard from Coles de Samuel is one of the largest Cu-based metal collections from the Late Bronze Age (LBA) (13th–8th centuries BC) ever found in Central Portugal, consisting of 18 artefacts which typologically display a strong regional identity. In the present study, an integrated multi-analytical approach combining Energy Dispersive X-Ray Fluorescence (EDXRF) analysis, Optical Microscopy (OM) and Scanning ...
MATERIAL CHARACTERISATION OF A FLORENTINE PAINTER IN PORTUGAL IN THE LATE 19TH ...
Bordalo, R; Bottaini, C; Moricca, C; Candeias, AThis paper presents the analytical characterisation of a series of paintings authored by Giorgio Marini (1836-1905) from the Museum of Évora. Marini was an Italian painter who lived in Portugal in the 19th century. He was a very prolific painter and his works, most of them portraits commissioned by urban and rural bourgeois and noble elites, are dispersed all over the country. The general good conservation stat...
Energy dispersive X-ray fluorescence spectroscopy/Monte Carlo simulation approa...
Bottaini, C; Mirao, J; Figueiredo, M; Candeias, A; Brunettti, A; Schiavon, NEnergy dispersive X-ray fluorescence (EDXRF) is awell-known technique for non-destructive and in situ analysis of archaeological artifacts both in terms of the qualitative and quantitative elemental composition because of its rapidity and non-destructiveness. In this study EDXRF and realistic Monte Carlo simulation using the X-ray Monte Carlo (XRMC) code package have been combined to characterize a Cu-based bow...
