    Describes a new technique for softening wood, using a 4 percent solution of ethylenediamine; a shortcut method for removing silica and crystalline materials with hydrofluoric acid; a method for rapidly neutralizing wood blocks which have been treated with hydrofluoric acid; and a method for maintaining the flatness of sections through staining, dehydration, and clearing. Methods described are applicable to wood with a specific gravity in excess of 0.75.
