Excimer nano-second laser-ablation inductively coupled plasma mass spectrometry (ns-LA-ICP-MS) is an important tool in chemical characterization of copper alloys. However, variable matrix induced elemental fractionation in copper alloys pose a significant challenge. Here, we systematically investigate this issue by analyzing the CHARM (Cultural Her...
Article
The application of organic protective coatings is the most commonly used strategy to avoid tarnishing of silver artefacts. Non-invasive mapping of coating thickness is a key point to evaluate the consistency and completeness of coating application and to monitor protective effectiveness over time. This work is aimed at evaluating the feasibility of...

Ochre-based pigments have been employed since the first artistic expressions of mankind, with widespread diffusion during the Roman civilization. Such prominent use influenced their technological development, focused on functional and aesthetic optimization through complex manufacturing procedures. Furthermore, their appearance is also influenced b...

A longcase clock attributed to Jean-Pierre Latz from the collection of the Cleveland Museum of Art was treated at the J. Paul Getty Museum in 2012. The clock is dated to 1744 and is decorated with Boulle-style marquetry and elaborate gilt-bronze mounts. As part of the treatment, the tarnished brass marquetry was to be cleaned and brought into visua...

This work presents the results of a comprehensive investigation of the “Tixi” carved lacquer micro-sample excavated from Zhejiang province in China (Son...
Thesis
Full-text available
Energy dispersive X-ray fluorescence spectroscopy (ED-XRF) is a method of elemental analysis that has numerous advantages for the study of cultural heritage materials. It is rapid, nondestructive, and capable of simultaneous multi-element analysis. In the last 15 to 20 years, miniaturization and mass production have made the technique widely availa...
Conference Paper
Objects made with decorative Asian lacquer are among the most highly prized collections in museums throughout the world. Exposure of Asian lacquer to light causes surface blanching and sensitivity to water and other solvents. This paper presents collective research on the photo-oxidation of Asian lacquer, in which lacquered objects and mock-up samp...

The Getty Institute recently acquired the Borghese-Windsor Cabinet (Figure 1), a piece of furniture extensively decorated with agate, lapis lazuli, and other semi-precious stones. The cabinet is thought to have been built around 1620 for Camillo Borghese (later Pope Paul V). The Sixtus Cabinet, built around 1585 for Pope Sixtus V (born Felice Peret...

Incralac is a clear coating designed as a lacquer for copper alloys in the 1960s by the International Copper Research Association and the British Non-Ferrous Metals Research Association. Incralac was adopted by conservators for the protection of outdoor bronzes and remains a popular choice in spite of mixed reviews on its performance. Over time, ma...

Noninvasive techniques have become widespread in the cultural heritage analytical domain. The popular handheld X-ray fluorescence (XRF) devices give the elemental composition of all the layers that X-rays can penetrate, but no information on how atoms are bound together or at which depth they are located. A noninvasive portable X-ray powder diffrac...

Rococo furniture decorated with fragments of Asian lacquer was highly fashionable in eighteenth-century France. The furniture's curvilinear designs forced cabinetmakers to manipulate flat lacquer elements so that they could be applied to a curved carcase. By removing material from the rear of lacquered wooden panels, they produced sheets of lacquer...

Identification of organic materials in Asian lacquers presents many challenges due to their complex formulations and the limited solubility of the main component, which is catechol-rich sap from three species of Anacardiaceae trees that crosslinks to form a hard film. Pyrolysis-gas chromatography–mass spectrometry with thermally assisted hydrolysis...

Rococo furniture decorated with fragments of Asian lacquer was highly fashionable in mid-eighteenth-century France. The furniture's curvilinear designs challenged cabinetmakers by forcing them to apply lacquered decorations – harvested from outdated, imported from Asia – furniture – onto curved sub-strates. The general approach was to remove materi...

Barrier coatings are widely used in conservation to add a measure of reversibility to an otherwise irreversible adhesive bond. Barrier materials are applied as thin films to mating surfaces prior to application of a primary (irreversible) adhesive. Subsequently, if reversal is required, the barrier layer can be softened or dissolved, releasing the...
