72751 - Characterization of Stone Materials

Learning outcomes

At the end of the course the student will acquire knowledge of the main pottery classes and of the evolution of manufacturing technologies from prehistoric to modern times. In particular, the student is able to: - define the mineralogical and geochemical composition and deterioration products of ceramic and stone materials; - identify the source and the composition of the raw materials and investigate their production techniques.

Course contents

Natural stone materials of ancient and modern employment (Granites, Marbles and Stones). Architectonic employment. Production and employment of ceramic materials (pottery and bricks). Binder, mortar, plaster, concrete and mosaics. Decay morphologies and deterioration mechanism. Sampling, cataloguing and elaboration of a diagnostic project. Mineralogical-petrographic study of natural and artificial stone materials through polarizing optical-microscopy (PLM), X-ray diffraction (XRD), X-ray fluorescence (XRF), scanning electron microscopy (SEM) end  EDS microanalysis, thermogravimetry-differential thermal analisys (TG-DTA), (DTG). Evaluation of experimental mineralogical and chemical data and their graphic representation.

Teaching methods

The course consists of lectures and laboratory exercises. The teaching activity will be developed in collaboration with sector’s specialists of the Bologna University and will be supplemented with visits at monuments.

Assessment methods

The final exam consists of a paper dealing with a topic 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 adequate grade or to a negative evaluation.

Teaching tools

LCD projector for Power Point presentations. Collections of rocks samples and thin sections of rocks, bricks, mortars and ceramics. Transmitted Polarized Light Microscopes, photomicroscope with digital camera, XRD, XRF and SEM-EDS. Thermogravimetry-differential thermal analisys (TG-DTA), (DTG).
