Archival

1. What makes paper archival? Archival Qualities are a function of two properties; The strength and durability of the cotton fiber and the chemical stability provided by an acid free sheet ( ph. of 7.5 – 9.5.). In the case of Byron Weston Linen Ledgers, an additional buffer (2% CaCO2) is added to ensure that it remains acid free after many years.

2. Why is 100% Cotton content important? The Cotton fiber is made up of pure alpha cellulose. Wood fibers have many impurities as well as the cellulose fiber. These impurities include tar, pitch and lignin among others. The chemical and mechanical processes that remove these impurities leave the wood fiber damaged and weak. These impurities, once removed are a hazardous sludge that must be carefully disposed of. Cotton is processed using only pure artesian well water and produces no toxic sludge. The cotton fiber, which needs no harsh processing, remains long, supple and very durable.

3. What about Acid Free Papers? Acid is the enemy of paper. It breaks down the molecular bonds between the fibers in a process scientists have called “Slow Fire” Acid free indicates that the ph. of the sheet is between 7.5 and 9.5. Paper made with this alkaline chemistry will last longer.

4. Why does Byron Weston make its sheet both 100% Cotton and Acid free? The 100% cotton will make a sheet durable enough to handle the abuses of handling by attorneys and title searchers, it is tough enough that it will not tear out or abrade. The Acid Free Properties provides the permanence.
