“…This combined approach allowed us to highlight more matching between SEM-EDS greyscale images, where it is difficult to distinguish the single-colored layers, and color images from reflected and UV light microscopy. The results of these analyses are summarized in Figure 6, where the samples representative of different surface colors found in the painted wall (green, red, and pink) are shown [38]. The collected EDS spectra are reported in Figures S2-S4.…”

This study focuses on the Memorial Chapel, a historical site located inside the Tempio Evangelico Valdese in Florence. In 1843, the first Anglican church in Florence, known as Holy Trinity Church, was built by D. Giraldi. Around 1892, G. F. Bodley began the reconstruction of a new building of neo-Gothic style at the same site, which was completed in 1904. This new church had a space dedicated to memory called Memorial Chapel. In 1967, the monumental complex was acquired by the Waldensians, now known as the Tempio Evangelico Valdese. This interdisciplinary investigation aimed to study the most damaged painted walls of the chapel. For this purpose, samples of decorative plaster mortars were collected from various points, after carrying out a digital mapping of the degraded areas. Mineralogical, petrographic, optical, chemical, and microchemical analyses were performed. This study made it possible to highlight the composition and the characteristics of the different layers of the plaster mortars, permitting us also to identify the types of pigments used over time in the paintings; furthermore, it was possible to reconstruct the degradation phenomena on the walls and the events that caused them, providing valuable insight for targeted restoration efforts.
