Abstract

A high ratio of broken to unbroken fibers in macerated wood samples has generally been considered to indicate the presence of minute compression failures and hence brittle heart in wood. It has been found that agitation during maceration produces broken fibers. The counting of broken fibers from macerations is therefore questionable as a technique for quantifying brittle heart and hence the brash-ness of wood.
