The process of crystal growth from solution can be divided into two main stages: bulk diffusion and interfacial reaction. The concentration of an agitated solution is considered to be the same as the bulk concentration C everywhere. But near the surface of the crystal, there is often a thin fixed solution layer, which is called the stagnated coating or diffusion …

For example, in the case of table salt (NaCl), the crystals are made up of cubes of sodium (Na) ions and chlorine (Cl) ions. Each sodium ion is surrounded by six chlorine ions.Our goal is to control this process – to make the crystals that grow as beautiful as possible. But first, we need to make our saturated salt solution. Prepare a pot of hot water, and add 40 g of salt for every 100 ml of water. Stir until most of the salt has dissolved.
