The Use of Portable Raman Spectroscopy to Identify Conservation Treatments Applied to Heritage Stone

Non-destructive in situ analysis of materials is highly desirable in cultural heritage studies, for it precludes the need for intensive sampling. The present study focused on the usability of Raman spectrometers, which can provide such analysis, in the identification of conservation treatments applied to stone materials forming part of the architectural heritage. Two products commonly used to c...

Alcohol dispersions of calcium hydroxide nanoparticles for stone conservation.

Alcohol dispersions of Ca(OH)2 nanoparticles, the so-called nanolimes, are emerging as an effective conservation material for the consolidation of stone, mortars, and plasters present in old masonry and/or mural paintings. To better understand how this treatment operates, to optimize its performance and broaden its applications, here we study the nano and microstructural characteristics, carbon...
