Learning Objectives

The aim of the course is twofold: (a) to verify the thermodynamic conditions in which an artwork  is realized and undergoes degradation and the conditions that allow it to be restored conservatively. For this purpose, not only the thermodynamic functions and their dependence on environmental conditions are illustrated, but also methods of quantification, extraction and purification of dyes and adsorption processes on a painted surface; (b) to describe, starting from the theoretical and operational bases, the chemical-physical spectroscopic techniques and to give examples of their use in the cultural heritage and restoration of artistic artifacts.

Program

  • Artworks and energy stabilization. Various forms of energy and its conservation. Isolated and open systems. Principles and functions of thermodynamics. Enthalpy, entropy and free energy. Examples in the field of cultural heritage. Reference conditions. Chemical potential and equilibrium conditions: example of a particle on a dye. 5 hours
  • Liquids: structure, flow, viscosity and diffusion. Mixtures and mixing. Colloids and surface tension. Extraction and purification processes to separate, quantify, extract and purify dye mixtures, with different solvents and with the same solvent (osmosis). Colligative properties. 5 hours
  • Solid state. Surface adsorption (on solid and liquid surfaces) and surface effects, with particular reference to deterioration of artworks. Catalysis. Transitions of the I and II order. Phase diagrams. Distillation for partially and completely miscible liquids. Chemical kinetics: steady state and transition state. Interactions between particles. 5 hours
  • Chemical-physical techniques and methods for the study of materials that constitute cultural heritage. Introduction to "destructive" chemical physical methods: granulometric and volumetric analysis, calcimetry, calorimetry, differential thermal analysis, thermogravimetry: examples applied to the materials used for the realization of artworks (such as pigments, gypsum, marble and ceramic materials). Evaluation of humidity and related chemical and physical phenomena of efflorescence and deliquescence. 3 hours
  • "Non-destructive" chemical methods (spectroscopic techniques): the theoretical bases of quantization for evaluating energy levels in UV-Vis. Example of CO (retinal) in UV-Vis. Vibrational resolution in UV-Vis and explanation of Fluorescence. 6 hours
  • Laser. IR spectroscopy: energy of vibrational levels and obtainable information. Rotational resolution. FT-IR. RAMAN spectroscopy. Magnetic resonances. Diffraction X. Fluorescence X. 6 hours
  • Examples from scientific literature of spectroscopic analysis of paintings, frescoes and pottery for the exam. 2 hours
  • Bridging Courses

    Learning Achievements (Dublin Descriptors)

    - The student will have to show the mastery of the basic knowledge related to the fundamental chemical-physical concepts, also related to the chemical-physical investigation techniques. Also the ability to evaluate processes of interest in the field of cultural heritage with chemical-physical logics

    - The student will have to show the understanding of the concepts and theories provided by the course; will provide examples of evaluation of simple processes that identify dynamics and interactions of particles and dyes and examples of deterioration and conservative revaluation of works of art with chemical-physical methods and use of techniques such as UV-Vis, fluorescence, IR, RAMAN and magnetic resonance.

    - The student must show possession of the ability to use knowledge and concepts that allow reasoning according to the specific logic of the discipline. It will have to be able, in particular, to identify methodologies that allow to know the chemical-physical processes that are involved in the installation and restoration of a work of art.
