The purpose of conserving an object is to stabilize what remains, and to slow down or stop its degradation. Conservation treatments should be reversible. Techniques may improve in the future, and what we do today should not hinder conservation efforts tomorrow. When an object is conserved, any information that has been lost is not reinvented (although the damaged area may be made neutral, so that the object can still be “read” as a whole).

Conservation considers an object’s age, provenance (history) and, most of all, its current state. The goal is to preserve what is left.”
