The article focuses on the importance of chemical analysis in the preservation of cultural assets. It highlights the significance of evaluating the chemical composition of objects and their interaction with the environment to understand decay signs and establish effective conservation strategies.
The study investigates efflorescences observed in two paintings, demonstrating challenges in identifying degradation processes of different origins. Through vibrational spectroscopy, scanning electron microscopy, and microbiological analysis, the migration of substances and microbial colonisation in paintings is examined. The research emphasises the role of chemical analysis in minimising degradation processes and preserving cultural heritage.
Efflorescences in paintings, such as Alfredo Volpi’s tempera on canvas and an oil mural painting in Mafra Palace, are studied to reveal the migration of calcium salts and substances from preparation layers. The article underscores the need for precise diagnostics to develop mitigation strategies, as seen in a previous study on Emmanuel Nassar’s painting.
Chemical analysis, including Raman spectroscopy, plays a crucial role in understanding degradation mechanisms and implementing effective conservation measures. The interdisciplinary approach of Heritage Science is essential for maintaining the memory, history, and artistic expressions that define a society’s identity through the preservation of cultural heritage. Overall, the research showcases the intricate relationship between chemical aspects, decay processes, and conservation strategies in safeguarding cultural assets for future generations.
