Lay summary

This research project 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. The goal is to provide basic essential knowledge about the materials constituting the cultural objects, about their degradation processes and their sensitivity to the environment, knowledge which in turn can be used by conservation scientists to examine efficiently specific cases.

Two research projects are presented, both focusing on the potential sensitivity of the material to the environment, namely: (1) Influence of the substrate on light- and anoxia-induced fading of the pigment Prussian blue and (2) Simulation of  corrosion phenomena in archaeological iron objects.

The two projects are expected to emulate further research in the domains of pigment-substrate-environment interactions and transport phenomena in porous ancient materials, respectively.
