Analysis of ancient materials and their degradation

CH-406

Lecturer(s) :

Gervais Claire

Language:

English

Remarque

According to the number of students (and interest), possibility to participate to the preparation and post-evaluation of a synchotron experiment (XAS scheduled in October or November).

Summary

This course aims at introducing ancient materials and their investigation by non-destructive synchrotron and imaging techniques. Case-studies on paintings, ceramics, stained glass, fossils will be presented and important concepts introduced and discussed (multiscale, heterogeneity, representativity)

Content

  1. What are ancient materials?
  2. Challenges in analyzing heterogeneous and sensitive materials
  3. Synchrotron techniques for ancient materials (X-ray absorption spectroscopy, X-ray fluorescence, photoluminescence)
  4. X-ray tomography techniques: Going to 3D and 4D imaging
  5. Physico-chemistry of materials degradation
  6. Case-studies of ancient materials and their degradation

Examples of case-studies:

' Cobalt blue degradation in oil paintings.
' Identification of archaeological ivory and its degradation.
' Nanoinvestigation of 19th century daguerreotype photographs.
' Initial corrosion processes in reinforced concrete monuments.
' Fossilization and diagenesis processes.

Keywords

Cultural heritage; synchrotron techniques, degradation processes, X-ray absorption spectroscopy, tomography, 2D imaging
