72833 - Advanced Chemical Diagnosis of Heritage Materials

Course Unit Page

Academic Year 2019/2020

Learning outcomes

At the end of the course the student will acquire knowledge concerning the micro-methods suitable for the micro-destructive characterization of both the organic and inorganic components constituting art and archaeological objects of art. In particular the student will be acquainted with the most advanced sample preparation techniques and microchemical methods used for the characterization of micro samples of historical interest.

Course contents

  • Organic and inorganic substances in historical samples
  • Advanced non destructive techniques
  • Cross sections preparation
  • FTIR microscopy: principles and advanced set up
  • Raman microscopy: principles and advanced set up
  • Immuno based methods: principles and advanced set up

Teaching methods

The course will consist of classroom lectures with PowerPoint presentations and video

Assessment methods

The final exam consists of a discussion on the topics covered in class, aimed at the evaluation of the theoretical knowledge acquired during the course, the possession of a specific language and the acquisition of an organic vision of the topics covered in class.
Good or excellent grades can be achieved by students who demonstrate a critical knowledge of the subject, who are able to apply theoretical concepts to practical examples and make use of an appropriate language. Mostly mnemonic knowledge, limited abilities of synthesis and analysis and imprecise language lead to grades ranging from discrete to sufficient. Important gaps, inappropriate language, lack of an overview of the topics covered will inevitably lead to a barely adeguate grade or to a negative evaluation.
