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…
Preferential Root Tropism Induced by Structural Inhomogeneities in 2D Wet Granular Media
Cesare M. Cejas, Lawrence A. Hough, Raphaël Beaufret +3
We investigate certain aspects of the physical mechanisms of root growth in a granular medium and how these roots adapt to changes in water distribution induced by the presence of…
Data Fusion of Objects Using Techniques Such as Laser Scanning, Structured Light and Photogrammetry for Cultural Heritage Applications
Citlalli Gamez Serna, Ruven Pillay, Alain Tremeau
In this paper we present a semi-automatic 2D-3D local registration pipeline capable of coloring 3D models obtained from 3D scanners by using uncalibrated images. The proposed pipel…
Web-Based Visualization of Very Large Scientific Astronomy Imagery
Emmanuel Bertin, Ruven Pillay, Chiara Marmo
Visualizing and navigating through large astronomy images from a remote location with current astronomy display tools can be a frustrating experience in terms of speed and ergonomi…
Diffusion Of Indigo Molecules Inside The Palygorskite Clay Channels
Catherine Dejoie, Pauline Martinetto, Eric Dooryhee +6
The search for durable dyes led several past civilizations to develop artificial pigments. Maya Blue (MB), manufactured in pre-Columbian Mesoamerica, is one of the best known examp…
Association of indigo with zeolites for improved colour stabilization
Catherine Dejoie, Pauline Martinetto, Eric Dooryhee +6
The durability of an organic colour and its resistance against external chemical agents and exposure to light can be significantly enhanced by hybridizing the natural dye with a mi…
Ceramics with metallic lustre decoration. A detailed knowledge of Islamic productions from 9th century until Renaissance
Delhia Chabanne, Marc Aucouturier, Anne Bouquillon +5
This paper describes research on the technological evolution of glazed ceramics with a metallic lustre decoration starting from their emergence in the Near East until the Hispano-M…
Revisiting Maya Blue and Designing Hybrid Pigments by Archaeomimetism
Catherine Dejoie, Eric Dooryhee, Pauline Martinetto +9
Maya Blue is actually one of the best known examples of an organic-inorganic hybrid material. Yet despite 50 years of sustained interest, its microscopic structure and its relation…
Redispersible Hybrid Nanopowders: Cerium Oxide Nanoparticle Complexes with Phosphonated-PEG Oligomers
L. Qi, A. Sehgal, J. -C. Castaing +4
Rare earth cerium oxide (ceria) nanoparticles are stabilized using end-functional phosphonated-PEG oligomers. The complexation process and structure of the resulting hybrid core-sh…
Towards truly simultaneous PIXE and RBS analysis of layered objects in cultural heritage
C. Pascual-Izarra, N. P. Barradas, M. A. Reis +5
For a long time, RBS and PIXE techniques have been used in the field of cultural heritage. Although the complementarity of both techniques has long been acknowledged, its full pote…
