Analytical Methods for the Environmental Degradation of Cultural Heritage
A.Y. 2022/2023
Learning objectives
The course provides an introduction to instrumental techniques of chemical analysis and structural characterization of cultural heritage materials, focusing on the environmental effects on such materials and paying particular attention to experimental aspects and data interpretation. The aim of the course is therefore to make the student understand what compositional and structural information can be obtained from this type of investigations on the original materials and their degradation products.
Expected learning outcomes
Ability to interpret and use analytical information from the findings and possibility of intervention for conservative purposes.
Lesson period: Second semester

Assessment methods and Criteria
The exam is based on a written test for each module, aimed to assess not only the acquired knowledge but also the capability of discussing critically a problem related to the subjects of the course.
The results of the test for each module are reported on the corresponding website.
The final mark, which is the average of the results obtained for the two modules, is communicated through the electronic service Vweb.
