Why is it important to use archival paper?
St Cuthberts Mill creates only archival papers. We understand that paper which isn't archival will degrade with age and become fragile and brittle. It may develop a yellow discolouration and brown spots. By using pure ingredients and ensuring the paper is alkaline (not acidic or pH neutral) with calcium carbonate buffering helps protect the paper.

| This paper was not archival and clearly shows discolouration and brown marks. |
Paper that isn't archival could contain much cheaper mechanical wood pulps (where the wood is ground up, and contains lignin that yellows), or it could be made with rosin and alum size (which is acidic).
All our papers are all archival and made to last!
