This work is part of a broader research line that aims to develop and implement nondestructive methodology for the chemical characterization archaeological metals based on protocol combines energy dispersive X-ray fluorescence spectrometry (ED-XRF) with Monte Carlo (MC) simulation algorithm. In this paper, ED-XRF-MC has been applied estimate composition selected group 26 copper-based artifacts fragments recovered at Perdigões, one larger Chalcolithic sites southwest Iberia. All analyzed have...
Energy dispersive X‐ray fluorescence (EDXRF) is widely used in the study of archeological metal artifacts, heritage and art history, where fragile nature objects requires use noninvasive techniques such as EDXRF, which addition, fast very affordable. An EDXRF analysis copper‐based artifacts from Late Bronze Age hoards Central Portugal presented. The measurements were carried out by using an tube with a Mo anode commercial Si‐PIN detector. data acquisition was performed keeping small...
This paper reports the diagnostic research of deteriorated paint layers from three mural panels made by Almada Negreiros found in Alcântara Maritime Station Lisbon. The aim was to understand main decay phenomena aid future conservation works. methodology comprised in-situ analyses technical photography Vis, Vis-RaK and UVF, p-OM h-EDXRF; micro sampling; OM, SEM-EDS, μ-XRD, μ-Raman, µ-FT-IR Py-GC/MS. Preliminary results show that all analyzed are affected salts (alkali sulphates) over time...
In recent decades, many works have been devoted to the study of materials and painting techniques used produce illuminated manuscripts. If analyses were once largely invasive, approach has become increasingly more in situ non-invasive over years. This work presents results analysis Portuguese Charter Évora, an manuscript that dates back 1501, combining elemental mapping technique (MA-XRF) with imaging infrared reflectography digital microscopy. Remarkably, this allowed us obtain unexpected...
Abstract A multidisciplinary approach has been applied to investigate the production technology of a collection copper-based artefacts found during archaeological excavation campaigns carried out in Almohad neighbourhood Mārtulah, Islamic name modern Mértola (South Portugal). In stark contrast other materials same site such as common and finely decorated pottery, glass, bone artefacts, metal objects have received less attention despite high number recovered. This study focuses on chemical...
The outdoor sculpture of the first Portuguese king, D. Afonso Henriques (~1109 – 1185 AD), placed in Guimarães (North Portugal) is one most emblematic national sculptures. Created 1887 by António Soares dos Reis, it possesses a remarkable symbolic value presumed birthplace king. In addition to artistic and heritage importance monument, few sculptures cast industrial foundry 19th-century. This study obtained data on sculpture's elemental composition corrosion...
In the present work, a fragment of stone mould recently found in Galicia (NW Spain) was studied by multiple analytical techniques approach involving 3D optical imaging reconstruction to obtain data about shape mould, typology artefact produced, and distribution black residue at surface pXRF, SEM-EDS, micro-FTIR, micro-Raman investigate nature residue. The study shows that likely used for socketed axes with side loop, originally composed two valves one core, it might have been subjected...
The outdoor sculpture of the first Portuguese king, D. Afonso Henriques (c. 1109–1185 AD), placed in Guimarães (North Portugal), is one most emblematic national sculptures. Created 1887 by António Soares dos Reis, it possesses a remarkable symbolic value presumed birthplace king. In addition to artistic and heritage importance monument, few sculptures cast industrial foundry 19th century. This study obtained data on sculpture’s elemental composition corrosion products, gathering important...
The dataflow in any scientific research laboratory is continuous and considerable even analytical niches such as heritage science laboratories. This article discusses advantages of using a Laboratory Information Management System (LIMS) for organising systematising an interdisciplinary laboratory. LIMS solutions are proven to be effective managing laboratories, their daily management tasks, improving work conditions increasing productivity, equipment resources, safeguarding data. software...
The aim of this paper is to provide a chemical study and microscopical characterization group metals from Late Bronze Age (LBA) found at Porto do Concelho (Central Portugal) consisting 2 sickles, palstaves, 3 spearheads, 5 swords, 4 daggers, 16 rings, 1 fibulae, bracelets undefined objects (fig. 1) [1].For purpose, multi-analytical approach was adopted by integrating micro-structural data: compositional measurements were performed using portable XRF Analyser, Metorex X-Met 920, equipped with...
A recently funded project aims to investigate and identify the primary ore sources employed in production of copper during Later Bronze Age (1500–800 BC) Ireland. We introduce its objectives, with a focus on analytical methodologies.
A diachronic, multi-analytical approach combining EDXRF, µFTIR, µRaman, SEM-EDS, and Py-GC/MS has been adopted with the aim to study for first time painting materials used decorate Egyptian funerary masks sarcophagi ranging from Late Period Roman stored in Archaeological National Museum (MNA) Carmo (MAC) of Lisbon Natural History University Oporto (MNH-FCUP). Results indicate that yellow red ochres, realgar, cinnabar, blue, green were as pigments while chalk served preparatory layer. Over...
