Course objectives
Current methods of conservation of cultural heritage used in museums are usually based on mechanical or chemical cleaning. They often cause rather degradation of objects than their restoration. Today, the low temperature plasmas generated by such electrical discharges have already demonstrated their potential also for surface modification of various materials and are emerging as a very flexible concept to regeneration of surfaces. For example, an application of low pressure hydrogen plasma allows fine regeneration of corroded metal artefacts and leads to preserving the original relief of the object at the minimization of its mass losses. Similarly, other procedures based on modern physico-chemical processes offer an alternative to current methods. Lasers, atmospheric pressure plasmas, lyophilization etc., have been used to treat glass, stone, paper or polymer materials. The aim of the course is to acquaint students with the basic principles of these methods.
Learning outcomes
Student will be able to:
- focus on current scientific knowledge of plasma technology for conservation and restoration purposes;
- orientate in the basics of plasma-chemical reactions and their influence on materials;
- orientate in the use of laser for the purposes of preservation and restoration;
- focus on the drying of wet materials (paper, wood, textiles etc.) using modern procedures based on lyophilization and vacuum technology
