  • 1Description

The 25-pack black 5 x 7" 4-Ply 100% Cotton Museum Board from Archival Methods is suitable for matting, mounting, and preserving valuable documents, fine prints, and photographs. When used for window mats and mat backing for small prints, the 4-ply thickness of each museum board provides a 1/16" separation between artwork and glazing, thus providing flat and sturdy support. Made of 100% cotton fiber without any brightening agents, this museum board is acid and lignin-free and ensures protection against the destructive effects a polluted environment might cause as your artwork ages.

100% cotton fiber pulp (99% alpha cellulose). It does not contain any post consumer waste recycled pulp. Paper is free of metal particles, waxes, plasticizers, and residual bleach peroxide. Sulfur content is less than 0.0008% reducible sulfur. Iron content does not exceed 150ppm and copper does not exceed 6ppm. No optical brightening agents are used in the pulp.
Alkaline sizing is used for both internal and external sizing. No alum is used in the manufacturing process.
Buffered with calcium carbonate 2 to 3% alkaline reserve; pH 9 ± 0.5; and acid-free.
Color dyes are light-fast and non-bleeding.
Pass the PAT (Photographic Activity Test) ISO 14523 (formerly ANSI IT9.16).
