Pests - Insects, especially, thrive in environments with high relative humidity and moderate temperatures. Frequent, periodic inspections are the best way to monitor for pests turning your collection into their home. If a problem is detected early on, it is very possible your collection can be saved.

Term: Lignin An acid organic substance found in wood pulp. It is removed in the chemical pulping process, but is not removed in the manufacturing of low grade papers, such as newsprint. Lignin free products aid in preserving photographs, documents, textiles and other materials.
Questions & Answers: If you have any questions, please feel free to e-mail them to mail@archivalmethods.com or visit us on Twitter, FaceBook or LinkedIn. Q: For years I have used non buffered acid free rag mat board to mount my color photographs (type C prints). Is there a reason you do not sell non buffered board? A: We do not stock non buffered rag board. Current ISO standard 18902 calls for buffered board and paper will all photographic and ink jet materials. The only exceptions are cyanotypes and protein based textiles.
Non buffered board will not cause any harm to your photographs but it will over time shift to the acidic side of the pH scale as it is exposed to the environment and pollution. Once it reaches the high side of the pH scale it is recommended to replace the board. We have decided to only sell products that conform to ISO standards. Our buffered museum (100% cotton fiber) and conservation (alpha-cellulose pulp from purified wood fiber) boards are acid & lignin-free and use alkaline or neutral sizing. Both are buffered with calcium carbonate. This ensures protection from destructive effects of polluted environments that can cause the pH of paper to decrease with age.
