ANALYTICAL CHEMISTRY FOR CULTURAL HERITAGE
- Assessment methods
- Learning objectives
- Teaching methods
A basic knowledge of organic and inorganic chemistry and of the main analytical techniques is required.
Oral examination, which will evaluate the knowledge of the course program and the ability to plan diagnostic analyses. The final maximum score is 30/30 cum laude.
At the end of the course the student will acquire a basic knowledge of the analytical methods for the characterization of art and archaeological objects and of the decay phenomena of works of art. The main artistic techniques and materials used in the past will be introduced. In particular, the student will be able to plan an analytical sequence for the characterization of art materials and for the definition of the state of conservation of different cultural heritage supports.
Introduction to Conservation Science. Introduction to the main artistic techniques and materials. The analytical sequence. The sampling techniques. Non-invasive techniques (Raman and infrared spectroscopy, X-ray fluorescence). The sample preparation techniques. Morphological investigations (optical and scanning electron microscopy). Materials and element characterization (molecular and atomic spectroscopy, thermal analysis, X-ray diffraction). Surface characterization (X-ray fluorescence). Separation techniques (chromatographic methods). The decay phenomena of works of art. Planning the analytical campaign. Case studies.
The course is structured into 40 hours of classroom lectures, 24 hours of laboratory (characterization of samples by optical microscopy, infrared spectroscopy, scanning electron microscopy and X-ray microprobe, thermal analysis, X-ray diffraction) and field experiences (museums, historical center of Como).
