Book chapterRaman spectroscopy and secondary ion mass spectrometry were used to investigate chemical and structural changes in soda and soda-lime glass exposed to organic pollutants under ambient and accelerated ageing conditions. Raman spectroscopy reveals modiﬁcation of the glass structure non-destructively, in situ, and as a function of depth. The pollutants caused...

Journal articleOrganic acids were previously shown to be involved in the alteration of historic soda silicate glasses in humid atmospheres under museum storage conditions. The present study investigates the role of these pollutants on the visual, compositional and structural modification of soda silicate glasses. Replica glasses aged in humid or humid/acidic...

Journal articleRaman spectroscopy is a versatile technique that has frequently been applied for the investigation of art objects. By using mobile Raman instrumentation it is possible to investigate the artworks without the need for sampling. This work evaluates the use of a dedicated mobile spectrometer for the investigation of a range...

Journal articleThe role of the organic pollutants formic acid, acetic acid and formaldehyde in the alteration of unstable soda silicate glasses is examined through SIMS depth profiling of replica glass aged in polluted and non-polluted atmospheres under ambient conditions. The effect of different controlled atmospheres is compared to the polluted atmosphere...
