81836 - CHEMISTRY FOR RESTORATION

Scheda insegnamento

Anno Accademico 2017/2018

Conoscenze e abilità da conseguire

At the end of the course the student will be acknowledged about the chemical constitution and degradation behaviors of different heritage and restoration materials such as paintings (pigments, binding media, varnishes), metal/alloys and restoration materials (consolidants, fillers, protective coatings).

Programma/Contenuti

PAINTINGS and PIGMENTS: optical and chemical properties, pigment classification

BINDING MEDIA: physical, optical and chemical properties. Historical use. Proteins, glues, egg, casein, milk, polysaccharides, drying oils, modern synthetic binders.

SOLVENTS and SOLUTIONS: solubilisation processes, mechanisms, concept of solubility, solvent power, other properties of solvents (vapour pressure, boiling point, volatility, retention, surface tension, etc.)

CLEANING AGENTS and SYSTEMS: claasification of most common solvents, reactive solvents, enzymes, bacteria, ion exchange resins, laser cleaning, emulsion and surfactants, resin soaps, solvent gels.

VARINSHES, ADHESIVES, CONSOLIDANTS, FILLERS: natural resins, synthetic resins, waxes, versishes and protective coatings, adhesives, consolidants and fillers.

METALS and ALLOYS: constitution, production technologies, deterioration and conservation-restoration
