Coliseum project: Correlating climate change data with the behavior of heritage materials
A Cormier, David Roqui, Fabrice Surma +5
Heritage materials are already affected by climate change, and increasing climatic variations reduces the lifespan of monuments. As weathering depends on many factors, it is also d…
Thermal Reconversion of Oxidised Lead White in Mural Paintings via a Massicot Intermediate
Théa de Seauve, Sophie Bosonnet, Olivier Grauby +3
Lead white is the most ancient and common white pigment used in mural paintings. However, it tends to blacken with time due to its oxidation to plattnerite (\b{eta}-PbO2). Chemical…
Comparison of recent estimators of uncertainty on the mean for small measurement samples with normal and non-normal error distributions
Pascal Pernot, Jean-Paul Berthet
We review the alternative proposals introduced recently in the literature to update the standard formula to estimate the uncertainty on the mean of repeated measurements, and we co…
Continuous wave laser thermal restoration of oxidized lead-based pigments in mural paintings
Théa de Seauve, Vincent Detalle, Alexandre Semerok +5
Red lead and lead white are some of the most ancient and common pigments in mural paintings. However, they tend to blacken with time due to their oxidation to plattnerite (\b{eta}-…
Influence of ns-laser wavelength in laser-induced breakdown spectroscopy for discrimination of painting techniques
Xueshi Bai, Delphine Syvilay, Nicolas Wilkie-Chancellier +5
The influence of ns-laser wavelength to discriminate ancient painting techniques such as are fresco, casein, animal glue, egg yolk and oil was investigated in this work. This study…
Hyperspectral Calibration of Art: Acquisition and Calibration Workflows
Ruven Pillay, Jon Y Hardeberg, Sony George
Hyperspectral imaging has become an increasingly used tool in the analysis of works of art. However, the quality of the acquired data and the processing of that data to produce acc…
