AIMS AND CONTENT

LEARNING OUTCOMES

Module III aims to provide the fundamental knowledge for the use of the most important mineralogical-petrographic survey techniques useful in the diagnostics of cultural heritage, especially ceramics. For each technique the student will be able to understand the meaning of the data obtained, to identify the spectrum of application, the potential and above all the limits of applicability. The critical discussion concerning numerous real cases will be linked to the design of the most suitable multi-analytical approach strategies in relation to the problems of archaeometric characterization and degradation diagnosis.

AIMS AND LEARNING OUTCOMES

Module III intends to introduce the student to the identification and categorization of ceramic materials. The student will become aware of how to treat a geomaterial of historical-artistic value in the preparations useful for studying in optical and electronic microscopy. The student will be able to apply first-hand optical microscopy techniques and to obtain preliminary information on the nature and area of origin of the raw materials. The student will use exercises by scanning electron microscopy on the different geomaterials, in which he will demonstrate the analytical resolution of the analysis technique. The student will learn to draw morphological and compositional information from the material in the studio. Finally, national and international regulations for the description and characterization of geomaterials and their degradation will be presented and discussed with reference to examples in the historical and artistic construction.

TEACHING METHODS

Lectures in the classroom

Practical exercises under the microscope.

SYLLABUS/CONTENT

Sample preparation techniques for chemical-mineralogical analysis.
    Techniques for the preparation of thin sections of ceramic and archaeological materials, stone materials, mortars and plasters.
    Morphological analysis techniques: stereomicroscopy, microscopy in transmitted polarized light, and SEM-BSE on ceramic and stone mortar plasters.
    Microanalysis techniques: SEM-EDS on ceramic and stone mortars.
    Regulations for the description and characterization of natural and artificial stone materials, and their degradation.

Laboratory activities:

    Analysis and characterization of natural and artificial stone materials through stereomicroscopy, microscopy in transmitted polarized light, and SEM-BSE.
    Analysis of the petrophysical properties of natural and artificial stones (eg determination of volume, density, porosity, capillary absorption, etc.).
    Analysis of the deterioration of natural and / or artificial stone artefacts through the mapping of materials and degradation.

EXAM DESCRIPTION

Written, Oral

ASSESSMENT METHODS

The assessment is based on a written task. The topic to be discussed concerns the topics of teaching. The teachers evaluate the ability and the critical sense in dealing with a theoretical diagnostic problem with the survey methodologies studied and practiced. In particular, the ability to integrate the knowledge acquired in the 3 modules of the course is evaluated.
