Experiments that clearly demonstrate significant differences in the solubility of different faces

Abstract

Although at present there is hardly any disagreement between specialists on the issue indicated in the title, it still seems impossible to point to direct experience that imediately resolves this issue beyond any doubt. Concerned about this form of experience, I focused on such a simple and convincing one that I can consider the goal achieved. According to the idea that was developed in my article “Observations and Experiments on Crystallogenesis,” solubility in relation to each face of a crystalline substance is directly proportional to its network density, and therefore, the more complex the symbol of the observed face (with the correct installation of the crystal), the smaller it is, and for irrational faces it is even equal to zero
