What is acid-free and lignin-free?
Acid is a chemical agent used during the manufacturing of paper that causes paper and photos to deteriorate. Disintegration can be slowed dramatically when acid is removed from paper during manufacturing. Lignin is an agent that holds wood fibers together in a tree. Newspaper has a very high lignin content and starts to become brittle and yellow after only a few days. Lignin can also be removed during manufacturing of scrapbook materials to make them photo safe. Products used by Heather are acid-free and lignin-free whenever possible.
