Conservation

Preservation from loss, damage, or neglect, stabilizing chemically and structurally, sustaining the survival of objects as long as possible in what is closest to their original form. The application of science to the examination and treatment of objects, and to the study of the environments in which they are placed — used, transported, and stored.

What differentiates art conservation from art restoration is the conservator's avoidance of adding anything to an object that cannot be easily removed or identified. Some also address restoration and other issues involving museology. (Artlex.com)
