An experimental study of the motion of the crystal front and the crystallization rate for a drop and a layer of an aqueous salt solution of LiBr was carried out. The nature of the crystal front motion depends on the initial salt concentration. For most of the crystallization time, the crystallization rate J cr is many times higher for a drop than for a thin layer. For the final crystallization stage, J cr is higher for the drop. Different crystallization kinetics is associated with a change in the place of origin of the first crystalline center, as well as with features of the temperature distribution on the free surface of the salt solution.
