37489 - PROCESSES IN CONSERVATION

Conoscenze e abilità da conseguire

At the end of the course the student will be acknowledged: - about both metal conservation-restoration processes and the use of the most advanced restoration technologies and research methodologies. Moreover, student will be informed about the metal restoration decision making processes and the role played by a conservation scientist. In particular the student will be familiar with the different metal conservation-restoration processes(diagnosis, cleaning, consolidation, structural reinforcement, surface protection, etc.; with the metal restoration materials, methods and terminology; - about both painting conservation-restoration processes and the use of the most advanced restoration technologies and research methodologies. Moreover, the student will be informed about the painting restoration decision making processes and the role played by a conservation scientist. In particular the student will be familiar with the different painting conservation restoration processes(diagnosis, cleaning, consolidation, structural reinforcement, surface protection, etc.) familiar with the painting restoration materials, methods and terminology.
