Preservation Calculator
Preservation Calculator for Photo Storage (in English, German, and Spanish)
Preservation Calculator
How good is your storage environment? How fast is your collection deteriorating? Will your current storage conditions encourage mold growth?
Preservation Calculator is a planning and analysis tool for collection storage environments in libraries, archives, and museums. Use it to:
- learn how temperature and RH affect organic objects in storage
- evaluate a given storage condition
- compare one storage condition to another
- plan new storage conditions
Organic materials (carbon-containing substances such as plastics, dyes, paper, plants, and animal products) make up a large proportion of cultural property collections. Preservation Calculator shows how temperature and humidity combine to influence the rate of decay of organic objects. It is concerned with two forms of decay: natural aging (caused by spontaneous chemical change within the material) and mold damage.
