According to the law of formation of crystal dissolution bodies formulated by W. Goldschmidt and F. Wright [Goldschmidt, Wright. 1904], the angles and vertices on the dissolution body of a crystal correspond to the poles of the faces present during its growth; the edges to the zones of the faces. This law is cited by A. E. Fersman [1955] as a rule by which the forms of crystal growth should be distinguished from the forms of dissolution. In 1958, F. Frank showed that if the dissolution (growth) rate is a function only of the orientation of its surface, then during dissolution (growth) of a crystal, a point on the surface of a given orientation has a rectilinear trajectory directed perpendicular to the surface of the polar diagram of inverse dissolution (growth) rates of the crystal at the corresponding point.
