This study investigates the potential of fatty acid methyl esters (FAME) as environmentally sustainable alternatives to traditional solvents for the removal of low-polarity materials commonly found in cultural heritage artefacts. Recognizing the environmental and health concerns associated with conventional solvents, this research focuses on FAME to remove low/non-polarity or non-polar substances used in cultural heritage preservation. Laboratory samples coated with low molecular synthetic resins (LMW) such as Regalrez 1094 and microcrystalline wax were treated with FAME applied in gel to prevent solvent–substrate interactions. Photographic documentation under UV-vis light, optical microscope observations, and spectrocolorimetric analysis were used for assessing surface “cleanness”, while FTIR-ATR spectroscopy was used to detect possible residue from treatment. Moreover, SEM analysis was used for a better understanding of the results. The best results were obtained using FAME base on methyl stearate according to Hansen-RED.

“Atmospheric” painting stands as a new frontier in contemporary art, presenting challenges and new considerations in museum practices. This article aims to analyze the possible evolution of four atmospheric paintings created by artist Luca Vitone during their transition from exhibition halls to the storage facilities of the MAXXI museum. The presence of active microbiological consortium raises question regarding the potential interaction these artworks may have with the surrounding environment. The year-long monitoring involved macroscopic and microscopic observation, spectrophotometric analyses, and cell vitality assessments using a bioluminometer. Additionally, the collected data were correlated with the prevailing microclimate within the storage. Indeed, the canvases underwent an evolution during their transfer to the storage; it was mainly the photosynthetic part of the consortium that underwent the greatest changes, resulting in changes in the color tones of the canvases. The viability of the cells in the consortium also underwent changes as indicated by measurements obtained with the bioluminometer. The monitoring has provided invaluable insights into the dynamic evolution of Vitone’s artworks and allowed the authors to hypothesize some strategies for the conservation of these types of artworks.
