The conservation-restoration of an artifact involves modifying it (a little or a lot).
"Conservators Delivering Change" by Jane Henderson (2022, #OpenAccess).
"Conservation interventions on objects are the most obvious changes arising in conservation practice: whether altering the rates of decay, making a repair, or revealing information, the tangible or intangible aspects are changed. Beyond this there are several realms in which conservators could deliver change: from change in their own approach and practice, leading change in teams, changing the institution and finally changing broader social structures."
