Archivists use a basic vocabulary to describe the preservation-quality supplies used in their work. Make these terms part of your Archivist’s Toolbox to help you easily select the best containers to store your family materials. Acid refers to the pH of a product, often paper or heavy-weight paperboard. Acid migration occurs when high-acid materials, such as newsprint, come into contact with other items and cause brown stains or a change in colors. Acid-free, true “archival” products are free of wood-pulp and other organic materials that can damage paper, photos, and artifacts. These products have a pH of 7.0 or more and have been made from non-wood pulp products or been treated to neutralize any acid. Lignin-free or low-lignin items are free or limited amounts of lignin, an organic substance that can cause acid to form in storage containers over time. Buffered archival paper has been treated to neutralize the potential build-up of acid over time. The most common buffering agents are calcium carbonate and magnesium carbonate. Photographic Activity Test (PAT) is a standardized test to determine how photo storage materials interact with photographs. Polyester, polyethylene, and polypropylene are chemically inert plastics and acceptable for sleeves and enclosures. Any plastic containing polyvinyl chloride (PVC) is not recommended. |
