Conservation. Protection Résumé : ABSTRACT In the last few years, the study of the surface color of historical buildings has progressed as part of conservation and restoration efforts to comply with the aesthetics of historical and pre-existing materials. The main critical element related to this type of study is represented by the succession of various interventions of restoration and maintenance over time that has altered the original aesthetics of monuments by using materials and colors selected according to criteria, trends, and needs of succeeding historical eras. In this paper, the investigation of plasters and colored finishing layers applied on two historical buildings located in Rome and dating to the early 1900s is reported. Results were obtained through a specific diagnostic investigation plan focused on microscopic, morphological, and chemical characterizations of plasters and colored layers detected on the monument surfaces. All post-intervention phases and dates have been identified by comparing the results obtained with historical data. Important information was uncovered that helps in tracing the original aesthetic conception of the buildings and in planning restoration approaches which can be compatible both aesthetically and materially with the original work.

Handling ‘Poison Books’: Dry Versus Wet Scenarios in Studies in conservation, Vol.70 N°7-8(2025; October-November) (2025-10-01)

Conservation. Protection Résumé : Toxic heavy metal pigments are known to be found in nineteenth-century, mass-produced, Euro-American bookbindings. A lack of data, standards, and regulations for exposure to heavy metal pigments in the cultural heritage sector limits understanding of when such bookbindings might present the greatest health and safety risk and how best to assess such risk. This case study measures the friability of arsenic, chromium, and lead based pigments in a sampling of nineteenth-century bookbindings through three scenarios: first, in their naturally aged, intact state; second, during a water event simulation; and third, after salvage and air-drying from the water disaster simulation. The data demonstrate that the risk of exposure to these heavy metals increases during and after a water event, with exposure to arsenic presenting the highest degree of risk.

Microscale Physical and Mechanical Analyses of Distemper Paint : A Case Study of Eidsborg Stave Church, Norway in Studies in conservation, Vol.68 N°1-2(2023; January-February) (2023-01-01)

Conservation. Protection Résumé : This study focuses on the use of micro-sensitive methods – nanoindentation, dynamic water vapour sorption, and X-ray microtomography – to examine the physical properties of small volumes of artists’ materials. The novel methodology proposed in this paper was tested on laboratory-prepared chalk-based ground samples and subsequently applied to distemper paint samples taken from the polychrome walls of Eidsborg stave church. This article discusses key parameters that can be used to inform macro-sized mock-ups mimicking physical and mechanical behaviour of artistic materials, and highlights limitations of such an approach for highly heterogeneous paint systems. Dynamic water vapour sorption measurements allowed determination of the pigment volume concentration (PVC) of distemper paint from Eidsborg stave church as 95%. To the authors’ knowledge, this represents the first assessment of PVC for historic distemper paint using a non-destructive experimental technique, which can be extended to other hygroscopic samples of known composition.

The Significance of the Citizens Theatre Paint Frames in Studies in conservation, Vol.70 N°5-6(2025; July-August) (2025-07-01)

Conservation. Protection Résumé : ABSTRACT A paint frame is the vertical structure on which a canvas is hung to allow a scenic artist to paint over a very large area. The Citizens Theatre paint frames are one of the few original working examples in Britain. Samples taken from these frames are made up of multiple layers of paint which have accreted over 100 years as paint flicked off brushes, rollers, and latterly spray guns while the cloths were being painted. Cross-section microscopy, micro-Fourier transform infrared spectroscopy (μ-FTIR) mapping and scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDX) were used to characterise these layers. Using the results in combination with archival research into scenic art suppliers/manufacturers, newspaper reviews of theatrical performances, and oral histories of scenic artists it has been possible for the first time to relate change in pigments and media within the paint layers with trends in scenic painting practice. This is one aim of ongoing research into the history of British scenic art (https://powertotransform.gla.ac.uk/) connecting the material history of the paint frame, theatrical cloths, and the lives of the scenic painters.
