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.

Vapeur, Technique de laMots-clés : Concentration pigmentaire volumique (CPV) Sorption Dynamique de Vapeur d'eau (DVS) Index. décimale : 7.025 Dommages. 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.
