Applicazione di dispersioni idroalcoliche di nanocalce a due casi studio: i Graffiti del carcere dello Steri e un documento d’archivio della Gran Corte Arcivescovile di Palermo

Dispersioni idroalcoliche di nanocalce: sviluppo di nuovi metodi di sintesi e loro caratterizzazione

Consolidation tests on the graffiti of the Steri’s prison with nanotechnological Ca(OH)2 dispersed in iso-propanol

The combination of weathering and human activities often induce pyhisicochemical alteration on the surface of wall paintings. One of the most still largely used restoration techniques for these works of art, is based on the application of organic polymers. Due to their ability to stick detached and powdered pigments,these products provide an immediate consolidating effects. Unfortunately, both their aging and their pyhisicochemical incompatibility with the inorganic support can have serious consequences also causing further damage to the work of art. In this paper a new technological approach is presented based on the use of Ca(OH)2 nanoparticles dispersed in isopropanol. Some applicative t…
