Experimental production of sole markings

Abstract

Sole markings have been produced by pouring suspensions of plaster-of-paris and water into tanks containing settled clay or gelatine. The observed processes lead to new or modified hypotheses concerning the origin of dendritic ridges, longitudinal furrows, certain tool marks and frondescent marks. In other experiments, load structures were produced by sieving sand and plaster-of-paris mixtures on to settled clay of varying densities.
