This chapter illustrates the potential of using volatile binding media (VBM) in emergency contexts to secure works of art through a temporary consolidation that allows either a safe transport or an in-situ restoration.

They are requested to ensure adequate consolidation, to leave the composition, morphology, or structure of the object unaffected, and to be completely reversible.

摘要

This chapter illustrates the potential of using volatile binding media (VBM) in emergency contexts to secure works of art through a temporary consolidation that allows either a safe transport or an in-situ restoration. VBM are substances with adhesive and cohesive properties that at room temperature are solid, passing directly to the aeriform state by sublimation. They are requested to ensure adequate consolidation, to leave the composition, morphology, or structure of the object unaffected, and to be completely reversible. Cyclododecane (CDD) was extensively used in past decades, but, due to its recent limited availability, the identification of an alternative VBM is a challenging task. In this work, experimental activity focuses on characterizing the properties of either already known molecules (such as menthol) or less investigated materials (such as menthyl lactate). The application of VBM (melted or dissolved in solvents) on several substrates (wood, plaster, terracotta…) was explored to evaluate different parameters. These results will be useful to select the most adequate application protocol in different emergency contexts. Preliminary results of the use of the selected VBM on a wooden sculpture recovered after the 2016 earthquake are reported. Biocide activity of menthol, as a further property to secure artworks, was also studied.
