3. Abstract Educational Linkage Approach In Cultural Heritage Prof. René Van Grieken and Pilar Ortiz - UA- University of Antwerp - Belgium Welcome to Module 3 of ELAICH, You will study the meaning of Preventive Conservation. FOLLOW US!!!!!

4. Searching for the perfect shelter? Educational Linkage Approach In Cultural Heritage Preventive Conservation Prof. René Van Grieken and Pilar Ortiz - UA- University of Antwerp - Belgium

5. Educational Linkage Approach In Cultural Heritage Preventive Conservation CONSERVATION = maintaining a work of art in « good condition » Prof. René Van Grieken and Pilar Ortiz - UA- University of Antwerp - Belgium

6. Educational Linkage Approach In Cultural Heritage Preventive Conservation In addition to intrinsic parameters, often ENVIRONMENTAL FACTORS are important for conservation, even indoors (museums, cathedrals). Improving the environmental conditions (micro-climate and chemical pollution) around a work of art is now popular and called: « PREVENTIVE CONSERVATION » Prof. René Van Grieken and Pilar Ortiz - UA- University of Antwerp - Belgium

7. Educational Linkage Approach In Cultural Heritage Preventive Conservation PREVENTIVE CONSERVATION is defined as: ” the mitigation of deterioration and damage to cultural property through the formulation and implementation of policies and procedures for the following: appropriate environmental conditions ; handling and maintenance procedures for storage, exhibition, packing, transport, and use; integrated pest management; emergency preparedness and response; and reformatting/duplication, etc." Prof. René Van Grieken and Pilar Ortiz - UA- University of Antwerp - Belgium

8. Educational Linkage Approach In Cultural Heritage Preventive Conservation Correr Museum, Venice, Italy Problems with darkening of Bellini paintings !! An indoor case to study. Help us to understand it!! Prof. René Van Grieken and Pilar Ortiz - UA- University of Antwerp - Belgium

9. Educational Linkage Approach In Cultural Heritage The Case of Correr Museum, Venice, Italy Study the situation of the Museum. Near, near the sea !! Prof. René Van Grieken and Pilar Ortiz - UA- University of Antwerp - Belgium

10. Educational Linkage Approach In Cultural Heritage The Case of Correr Museum, Venice, Italy We took samples of the atmosphere inside the museum. Easy, just draw air through a filter !! And we got the particles that were around in the Museum. After we sent the filters to the laboratory. Prof. René Van Grieken and Pilar Ortiz - UA- University of Antwerp - Belgium

12. Educational Linkage Approach In Cultural Heritage The Case of Correr Museum, Venice, Italy Correr Museum: gypsum particles, calcium-rich particles, calcium-silicon particles, aluminosilicates, sea salt Calcium-rich particles more abundant with windows closed, no visitors, etc. Strange situation¡¡¡¡ Prof. René Van Grieken and Pilar Ortiz - UA- University of Antwerp - Belgium

13. Educational Linkage Approach In Cultural Heritage The Case of Correr Museum, Venice, Italy After a lot of searching, we founf the origin of the particles: Plastered walls are deteriorating and releasing particles Preventive Conservation SOLUTION: Cover walls with plastic paint or renew the plaster!! Prof. René Van Grieken and Pilar Ortiz - UA- University of Antwerp - Belgium

14. Educational Linkage Approach In Cultural Heritage The Case of Metropolitan Museum of Art in New York White deposits were noticed in and on showcases in some sections of the museum. After cleaning they re-appear quickly! Problem with indoor emissions, building materials, particle filtration or ventilation???
