Searching for the perfect shelter?

Preventive Conservation

CONSERVATION = maintaining a work

of art in « good condition »

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 »

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."

Correr Museum, Venice, ItalyProblems with darkening of Bellini paintings!!

An indoor case to study. Help us to understand it!!

The Case of Correr Museum, Venice, Italy

Study the situation of the Museum.Near, near the sea !!

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.

The results of analysis.

Calcium-rich particles more abundant with windows closed, no visitors, etc. Stra

The Case of Correr Museum, Venice, ItalyAfter 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!!

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???

Study the situation of the Museum.Inside Central Park¡¡

Ion Chromatography shows that the deposit is rich in nitrate:Ammonium nitrate from fertilizers in Central Park?Sodium nitrate from the reaction of seasalt wit nitrogen oxides from traffic?

Small NaNO3 particles originating from outdoors were found in the galleries, showcases and in the deposits as well:NaCl (seaspray) + NOx (traffic) → NaNO3

Problem with air filtration !

The Case of Wawel castle in Cracow, Poland

Problems of conservation during winter and without visitors.We took samples of the particles in air. Some of our aerosol sampling

equipment in the castle!

Study the situation of the CastleIn Cracow.

Results of single particle analyses (2-4 µm)Educational Linkage Approach In Cultural Heritage

NaCl in winter is from deicing

NaCl in Cracow!!!!

Preventive conservation based on XRS analysis:

No more de-icing of entrance path with salt, but manuallyMore mats and shoe cleaning at entrance.

New case…

Thank you!!!!We hope you can help us in the future.
