What conservation is
Conservation is the discipline of preserving and restoring a work, and the conservator's role is to keep the work in the best condition possible given its age and history. Conservation is distinct from restoration (the work of returning a work to a specific earlier state) and from repair (the work of fixing damage). A conservator's primary commitment is to the work itself, and the conservator's training emphasises minimal intervention and full documentation.
The American Institute for Conservation of Historic and Artistic Works (AIC) maintains a code of ethics and a directory of conservators, and the European Confederation of Conservator-Restorers' Organisations (ECCO) does the same for European conservators. A credible conservator is a member of one of these bodies, has documented training, and has experience with the artist's work.
When conservation is needed
The most common conservation events are condition checks at acquisition, before sale, before loan, and after any environmental event. A condition check at acquisition is part of the due-diligence process: the work is inspected, the condition is documented, and any treatment is identified. A condition check before sale is the seller's due diligence: the work is inspected, the condition is documented, and any treatment is identified for the buyer. A condition check before loan is the lender's due diligence: the work is inspected, the condition is documented, and any treatment is identified for the borrower. A condition check after an environmental event is the collector's response: the work is inspected, the condition is documented, and any treatment is identified for the insurance and the recovery.
Beyond these events, a credible conservator recommends a periodic condition check for every significant work in the collection, with a frequency that depends on the work's medium, age, and condition. Oil paintings on canvas typically need a check every three to five years; works on paper need a check every two to three years; sculpture and installation art need a check on a schedule set by the artist or the artist's estate.
Who does the work
The right conservator is independent, has documented experience with the artist's work, and is willing to write a treatment proposal and to document the work in writing. The conservator should also be covered by professional indemnity insurance, and the conservator's work should be covered by a separate fine-art insurance policy during the treatment.
The conservator's relationship with the artist or the artist's estate is also important. For a living artist, the artist may have a preferred conservator, and the artist's preference should be respected. For a deceased artist, the estate may have a preferred conservator, and the estate's preference should also be respected. The collector's conservator should be willing to coordinate with the artist or the estate, and the conservator's work should be documented in a form the artist or the estate can review.
The treatment proposal
A credible conservator writes a treatment proposal before any work begins. The proposal includes the work's current condition, the work's proposed treatment, the work's expected outcome, the work's timeline, the work's cost, and any conditions that may affect the outcome. The proposal is reviewed by the collector, by the collector's advisor, and (where appropriate) by the artist or the estate. The proposal is approved in writing before the work begins.
A treatment proposal that does not include the work's current condition, the work's proposed treatment, the work's expected outcome, the work's timeline, and the work's cost is not a complete proposal. A treatment proposal that the conservator has not signed is not a credible proposal.
The treatment record
The treatment is documented in a written record that is retained with the work's file. The record includes the work's condition before the treatment, the work's condition during the treatment (with photographs), the work's condition after the treatment, the materials used, the conservator's notes, and any conditions that emerged during the treatment. The record is signed by the conservator and is countersigned by the collector (or the collector's representative) at the conclusion of the treatment.
The treatment record is part of the work's documentation, and the work's documentation is part of the work's value. A work with a complete treatment record is a work that is easier to insure, easier to sell, easier to lend, and easier to pass on. A work without a treatment record is a work that has lost part of its value.
Conservation as a recurring budget
Conservation is a recurring cost of running a collection, not a one-time project, and the budget should be planned annually, not reactively. The annual conservation budget covers periodic condition checks, minor treatment at the time of the check, and a reserve for unexpected events. The reserve is typically 1 to 3 percent of the collection's value per year, with the actual spending depending on the collection's age, condition, and the materials of the works.
A collector who plans the conservation budget annually is a collector who can respond to conservation events without disrupting the rest of the collection. A collector who treats conservation as a reactive expense is a collector who pays more for the same work, and who often has to defer the work, which makes the work more expensive when it is finally done.
