The Characterization of a Fragment of a Medieval Fresco from Corbii de Piatră Cave Church

The fresco of the Corbii de Piatră Cave Church, dating from end 13th century and beginning 14th century, is applied to sandstone wall. degradation on large surfaces, with many areas detachment, has been determined by infiltration meteoric water through wall which it applied, as well temperature variations, repeated wetting/drying processes. However, there are small portions that show good adhesion present research, aimed at providing scientific data restorers historians, involves advanced characterization a fragment being carried out an interdisciplinary team. stratigraphy, microstructure, compaction defects, chemical composition, variation composition in pictorial surface mortar-sandstone interface were determined. Correlations established between processes adhesion.
