This proposal aims at developing a multidisciplinary approach to study fundamental chemical and physical processes responsible for the degradation of ancient materials, by means of advanced analytical procedures with an emphasis on synchrotron and computational techniques. The motivation lies in filling the current gap between conservation and fundamental academic research. Two research projects are presented, both focusing on the potential sensitivity of the material to the environment, namely: (1) light-induced fading of Prussian blue and (2) Simulation of corrosion processes in iron archaeological objects.
