Learning objectives

Let students know the basis of analytical techniques usually employed in petrology and geochemistry in the study of the works of art, which are built, at least in part, with geological stuff. These techniques is shown in both the diagnostic phase of degradation of the stuff and in the restoration works, with the aim to suggest a way to preserve the works of art in a restoration project and to indicate the place where to find suitable raw materials to employ in the restoration works

Prerequisites

Knowledge of the base concepts of inorganic chemistry and general mineralogy; systematic mineralogy as for silicates and oxides normally occurring in rocks and usually employed in pigments. Knowledge of the employment of the optical transmitted light mineralogy microscope. Basal knowledge on physics, as for electromagnetic waves. Knowledge of the basis of the inorganic chemistry.

Teaching methods

Outline of the general concepts in the analytical techniques. Description of analytical techniques, highlighting, for each of them, potentials and limits. Laoratory activities in both sample handling and sample analyzing, employing all the laboratories at the present available in the Earth Science Department of the University of Parma

Assessment methods and criteria

Oral exam: basis of concepts of analytical techniques; details on a specific analytical technique, and its possible employment in a project of restoration of a work of art
