One of the most interesting molecular phenomena in nature is known as crystallization. It is brought about in the arts of man and in nature by three methods. When a chemical salt, such as table salt, is dissolved in water and allowed to stand in a shallow dish until it dries, it will be observed that the solid residue appears as crystals. Those from common table salt will be cubical in form. However, every different salt will yield its own distinctly shaped crystal.
