COTTRELL MAT

Description

Cottrell Mat is a 100 percent rag board made with only the finest cotton linter fiber.  The product is acid free (acid neutral) and lignin free.  It is buffered with calcium carbonate.

Cotton Rag mats are historically used by museums and galleries because cotton is naturally free of acid and lignins.  The Cottrell mats are a solid sheet or board of cotton.

All Cottrell Mat products are buffered with calcium carbonate.  This ingredient retards the accumulation of acids.  Most cotton rag boards also have calcium carbonate added even though they are naturally “acid free”.  The calcium carbonate combats environmental pollutants that can increase acidity.

There are two types of mat board, standard mats and archival mats.  Standard mats are typically made with high alpha kraft (wood) fibers.  Archival mats are made from 100% cotton fibers to a much higher standard. The best archival mats are made from 100% cotton rag.
