The Restoration Operations

Scientific investigations will be carried out in multiple phases by the Scientific Research Office applied to Cultural Heritage of the Vatican Museums.
Initially, research will focus on the state of conservation and on degradation phenomena. During the works, the investigations will cover the types of interventions to be carried out. Towards the end, information on execution techniques and constituent materials will be gathered.
In the preliminary phase, however, patina samples will be collected in sufficient quantities and from different areas in order to carry out an exploratory analysis of their composition, primarily to understand the degradation phenomena by which they have been affected. In the final phase, alloy and possibly wood samples will be taken for more targeted investigations since all surfaces will be cleaned and easily inspectable.
