Garcia Vallès, MaiteVendrell Saz, Màrius2014-03-242014-03-2420020366-3175https://hdl.handle.net/2445/52916The glasses of the rosette forming the main window of the transept of the Gothic Cathedral of Tarragona have been characterised by means of SEM/EDS, XRD, FTIR and electronic microprobe. The multivariate statistical treatment of these data allow to establish a classification of the samples forming groups having an historical significance and reflecting ancient restorations. Furthermore, the decay patterns and mechanisms have been determined and the weathering by-products characterised. It has been demonstrated a clear influence of the bioactivity in the decay of these glasses, which activity is partially controlled by the chemical composition of the glasses.8 p.application/pdfengcc-by-nc (c) Consejo Superior de Investigaciones Científicas (CSIC).
