preservation criteria

Preservation criteria are set standards used to decide how well an object, document, or artwork has been maintained over time. They help determine if the item is safe from damage or decay, and whether it can still be enjoyed and studied in the future. These criteria include factors like physical and chemical stability, appearance, and how much they retain their original qualities. Essentially, they guide conservators in caring for items so that they remain as close as possible to their original state, ensuring long-term preservation and accessibility.
