Scope:

This method, based on the silvering method devised by Clark (1), is used to determine the specific exposed surface of unbeaten, or only slightly beaten, chemical pulps, groundwood, wood flour, and similar materials. It is not suitable for finely fibrillated or well-beaten fibers, since the silvering step causes some of the finest fibrils to collapse and hence lowers the exposed area (2).
