Home | Hobbies | Arts & Crafts Acidity is rated on a pH scale. Items that are pure and "acid-free" have a pH level of zero. Anything above zero indicates acidity. Of the items on your page must have a pH level of zero to fully protect your photographs. Acid migrates over time to neutral items, much in the same way as a cupful of hot water dropped into a bowl of cold water will disperse over time to create a medium temperature. Products that act as buffers between acidic items and photographs are available on the market, but these are not as safe as manufactures make them out to be. Over time, these papers cannot absorb the acid in most items, and it will eventually migrate to your photographs. A safe way to buffer acidic items from your photographs is with mylar, or polyester. This is the product most companies use to make page protectors, for that very reason. One of the major problems in the scrapbooking market is that there is no set standard a product must reach before being termed "photo safe." Therefore, that phrase is used very loosely, often at the consumer's expense. Your best bet is to use products labeled "archival quality," but even then only buy products from manufactures you know and trust. When buying from a new company, it is important to research the company first and even call customer service to ask about their product quality. Don't be shy; doing this will help protect the investment of time and money you made in your scrapbook. If you want to test your products, pH pens are now becoming readily available on the market. By making a mark on the back of your paper and comparing its color to a guide, you can tell if your paper is truly acid-free or not. Bottom line is, consumer beware.
