As cellulosic materials are very sensitive to acid degradation, an alkaline reserve is sometimes added to archival papers and treated papers to minimize acid-produced embrittlement, yellowing, and deterioration. For example, a paper may have a reserve of 10% - 20% precipitated calcium or magnesium carbonate, which is an alkaline substance. ]]></note></mads>
