The components of the interfacial surface tension of talc and pyrophyllite were determined by measuring the rate of the capillary rise of a number of liquids through thin, sedimented deposits of the powdered minerals. The rate of capillary rise of a liquid in a powder is related to the contact angle
formation of new closed loops. We thus have multiplication of dislocation loops and there is no necessity for nucleating new ones, although some may be nucleated at a distance from the existing ones. The observations of decorated dislocations in fluoritec4) suggest that such a mechanism can operate
