The 20 x 24" Archival Methods 4-Ply Pearl White Conservation Mat Board contains 15 boards designed for artwork, photographs and documents. The board is made of alpha-cellulose pulp from purified wood fiber and has a similar surface to mat board made from cotton pulp. Conservation mat board is more economical than traditional cotton paper with the same long-term stability.
These acid and lignin-free boards use alkaline or neutral sizing. The boards are buffered with calcium carbonate for added protection and longer life. Pearl white has a warmer tonality than bright white museum board and less yellow than antique white.
