Which is NOT a process of art conservation?

Appraising value is not considered a process of art conservation. Art conservation focuses primarily on the preservation and protection of artworks by assessing their condition, recommending protection measures, and suggesting restoration when necessary. These processes are all aimed at ensuring that artworks are maintained in good condition and can be enjoyed by future generations.

In contrast, appraising value relates to determining the financial worth of an artwork, which is more aligned with the fields of art valuation or appraisal, rather than conservation. Conservation professionals prioritize the physical and chemical stability of artworks, addressing issues such as deterioration and environmental risks, rather than assessing their market value. Thus, while valuing art is important in the art market and for insurance purposes, it is not a task associated with the conservation of art itself.
