Abstract

Specifies method based on the silvering method devised by Clark, used to determine the specific exposed surface of unbeaten, or only slightly beaten, chemical pulps, ground-wood, 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.
