Discussion

For traditional conservation purposes, any change to the determined ideal state of the object can be construed as loss. Loss can be identified in all object types, including documents, paintings, stone, wood, ceramics, etc. Typical types of loss include flaking on paintings or missing protrusions on sculptures.

If anything ever falls or comes off of an object, immediately put in a conservation-appropriate housing for future conservation and mark the folder or bag as a related fragment. Once the missing pieces are lost, it can be impossible to ever find the original piece and put back together again.
