The analysis of fossil bone thin sections by FTIR microspectroscopy allowed the characterization of diagenetic alterations at the histological scale.
Integrated X-ray and
neutron-based analysis of bronze artefacts from the Ligurian settlement of Guardamonte-Monte Vallassa
Integrated neutron-based and X-rays based measurements were performed on bronze archaeological findings form a pre-Roman settlement to investigate their composition in a non-destructive way.
X-ray powder diffraction for the imaging of (hidden) paintings
Imaging of pigment distributions in paintings and hidden under paintings by High energy X-ray powder diffraction.
Further metallurgical analyses on silver coins of Trajan (AD 98–117)
A marked decrease in the silver content of the alloy of Trajan's denarii between the years AD 99 and AD 100 could be observed
Reverse engineering the ancient ceramic technology based on X-ray fluorescence spectromicroscopy
To further our understanding of the evolution of ceramic technology, we used a micro-X-ray beam to map the mineralogy and iron valence distribution of ceramic samples.
Multi-technique characterization of ancient findings from Gela (Sicily, Italy)
The non-destructive and micro-destructive multi-technique approach used to study ancient Sicilian samples provided information to fully characterize the decorated surface.
The use of microscopic
X-ray diffraction for the study of HgS and its degradation products corderoite (α-Hg3S2Cl2), kenhsuite (γ-Hg3S2Cl2) and calomel (Hg2Cl2) in historical paintings
The use of microscopic X-ray diffraction for the study of HgS and its degradation products corderoite, kenhsuite and calomel in historical paintings.
New insights into alloy compositions: studying Renaissance bronze statuettes by combined
neutron imaging and neutron diffraction techniques
The material composition and crystalline structures of Renaissance bronze sculptures have been analyzed by combining Neutron Imaging and Neutron Diffraction techniques using SScanSS, showing that these objects can be magnetic.
Protrusions in a painting by Max Beckmann examined with confocal μ-XRF
The aim of this study is the investigation of the chemical reactions during the formation of protrusions in a painting by Max Beckmann.
Casting technology of Renaissance bronze statuettes: the use of TOF-neutron diffraction for studying afterwork of Renaissance casting techniques
The finishing techniques of Renaissance bronze statuettes are examined using Time of Flight Neutron Diffraction in order to prove that bronze sculptures could be cast without afterworking using chasing tools.
X-ray absorption spectroscopy study of the various forms of phosphorus in ancient iron samples
Ancient phosphorus-containing iron-based alloys are often reported to be strongly resistant toward corrosion. In this study, micro-XANES spectra highlight phosphorus distribution and speciation in two ancient iron-based samples.
A study on gold and copper provenance for Romanian prehistoric objects using micro-SR XRF
A provenance study for prehistoric gold and bronze artifacts in comparison with Au and Cu geological sources, using micro-SR XRF elemental analysis.
The darkening of zinc yellow: XANES speciation of chromium in artist's paints after light and chemical exposures
Color changes in artists paints containing Zinc yellow are associated with the reduction of Cr(VI) to Cr(III).
SRXRF-measurements at non-planar objects: automatic determination of the angle of incidence of the exciting X-ray
Non-planar sample shapes must be expected especially for art and cultural heritage objects. The use of a microscope and an easy algorithm allows the fast determination of the existing geometry.
About this collection
In this specially themed issue of JAAS, a collection of 25 papers has been gathered that were submitted as a result of an oral or poster contribution at the SR2A-2010 (Synchrotron Radiation in Art and Archaeology) conference. This meeting was organized by Koen Janssens (University of Antwerp, Belgium), Joris Dik (Technical University of Delft, Netherlands), Robert Van Langh (Rijksmuseum Amsterdam, Netherlands) and Janneke Ottens (Institute for Cultural Heritage, Amsterdam, Netherlands). The conference took place from 7–10 November 2010, and the venue of the meeting was the van Gogh museum, located at the Museum Square in central Amsterdam.
