Diagnostics and preservation of cultural heritage
Learning outcomes of the course unit
The course intends to give the student, within the framework of the European descriptors for the three-year degrees (Dublin descriptors), the tools to develop the knowledge and the capacity to understand the artistic good, through the study of the materials Original, Degradation and restoration (1st descriptor-Knowledge and ability to understand).
At the end of the course the student must be able to: • Apply such knowledge and comprehension skills in addressing, with a professional approach and through the conception of arguments, different questions of knowledge of constituent materials A work of art, • Knowledge of the original materials constituting a cultural good, • The processes of degradation that afflicge the artistic and cultural works,
• Appropriate materials and techniques of intervention conservatively of an artistic and cultural work,
• Elaboration of a conservative intervention protocol on the work of Art (2nd descriptor-Knowledge and comprehension skills applied);
• Independently collect and interpret articles, protocols of conservative interventions (3rd descriptor-autonomy of judgement);
• Communicating information, ideas, problems and solutions of conservation interventions of pictorial Works (4th Descriptor-communicative skills);
• Develop further learning skills necessary to undertake successive studies with a high degree of autonomy in the field of cultural heritage (5th Descriptor-Ability to learn).

Assessment methods and criteria
The assessment of learning provides for an oral interview on the teaching programme
Expected Learning Outcomes
To be able to evaluate the possibilities present in the chemical field for a suitable knowledge and valorization (preservation, recovery) of the historical-artistic cultural heritage. Know how to distinguish materials according to the chemical composition. Know how to understand the strengths (inertia, stability) and weakness (reactivity, instability) of the materials. From the physico-chemical properties of the substances constituting the study materials know how to recognize and evaluate the state of preservation and the potential causes of degradation.
