Long-term stability of materials in the art
Cultural objects, especially works of art, are constantly at risk of irreversible damage due to intensive exhibition politics, but also due to environmental pollutants and climate changes. These effects can lead to the complete destruction of the material, especially for outdoor objects.
The long-term stability of materials in the field of arts is tested by systematic investigations, weathering and light tests. Above all, methods of modern surface analysis are used, which make it possible to detect material changes already in the nanometer range. Finally, such systematic studies may suggest and test modern materials and procedures of conserving and preserving our cultural heritage.
