While the terms "conservation" and "restoration" are often used interchangeably, especially in common parlance, there are important distinctions, particularly when applied to archives and museums.
Conservation is a broader term that encompasses all actions taken to ensure the long-term care and preservation of cultural heritage.
Preventive Conservation (Preservation): This involves creating a stable environment for objects to minimize their deterioration.
Examples include: Controlling temperature, humidity, and light levels in storage and display areas.
Proper handling techniques.
Using archival-quality storage materials (acid-free boxes, folders, etc.).
Pest control.
Emergency planning.
Remedial/Curative Conservation (Intervention): This involves direct, hands-on treatment to stabilize an object and slow down deterioration.
The goal is to address existing damage without significantly altering the original. Examples include: Mending tears in paper.
Consolidating flaking paint.
Cleaning surfaces to remove harmful dirt or grime.
Stabilizing a broken object.
Restoration, on the other hand, is a specific type of intervention within conservation that aims to return an object to a known or assumed earlier state, often its original appearance or functionality.
Filling losses in a painting or ceramic.
Replacing missing parts of an object (e.g., a broken leg on a table).
Re-toning or repainting areas to match original colors.
Removing discolored varnishes.
Distinguishing Archives Conservation and Museum Restoration:
While both archives and museums engage in both conservation and restoration, their priorities and approaches differ due to the nature of their collections:
Archives Conservation:
Primary Focus: The core principle of archives is the preservation of information content and authenticity. Archival materials (documents, photographs, digital records, etc.) are primarily valued for the data and evidence they contain.
Minimal Intervention: Archives conservators are highly focused on minimal intervention.
They prioritize stabilizing the physical form to ensure the information remains accessible, and are less likely to undertake interventions that might obscure or alter the historical evidence, even if it makes the item "look better." Emphasis on Preventive Conservation: Due to the sheer volume and fragility of many archival materials (especially paper), preventive conservation is paramount. Proper storage, environmental control, and digitization efforts are crucial to ensure long-term access.
Examples of Archival Conservation:
De-acidifying brittle paper.
Mending tears in historical documents with reversible adhesives.
Encapsulating fragile maps or plans.
Creating preservation copies (microfilm or digital surrogates) of unstable originals.
Museums Restoration:
Primary Focus: Museums collect, preserve, and interpret objects for their historical, artistic, cultural, and aesthetic value.
While information is important, the physical integrity and aesthetic presentation of the object itself are often central. Greater Acceptance of Aesthetic Intervention: Museum conservators may undertake more extensive restoration to improve the visual coherence or completeness of an object, especially if it's intended for public display.
The goal might be to make the object more understandable or aesthetically pleasing to the viewer. Balance of Aesthetics and Authenticity: There's a constant tension in museum restoration between returning an object to an "original" state and preserving its historical patina and evidence of use. Modern conservation ethics emphasize making any restoration reversible and clearly distinguishable from the original material.
Examples of Museum Restoration:
Reattaching broken pieces of a ceramic vase and in-painting the filled areas to blend seamlessly.
Cleaning a discolored painting and in-painting small losses to restore its original visual impact.
Reconstructing missing parts of a historical costume.
In summary:
Both fields are guided by ethical principles that prioritize minimal intervention, reversibility of treatments, thorough documentation, and respect for the object's history and integrity.
