Simply pour one spoonful of your material at a time into the warm water and stir vigorously until it disappears. Ensure continued temperature control by placing a thermometer near each plate. As the solution cools the solubility of the product decreases and solute molecules come together to form small stable crystals called nuclei. Humidity: Humid air contributes water to the liquid and slows crystal growth. In warmer temperatures, the distance between molecules is greater, which allows crystals to form larger, purer shapes at a much more uniform rate than can occur at colder temperatures.

It may take a few days to get good crystal growth. This process is called crystallization and can happen when magma hardens or when water evaporates from a natural mixture too. Answer: If the saturated solution of a substance at a particular temperature is cooled to a lower temperature, then the solubility of the substance decreases and some of the dissolved substance will separate out in form of solid crystals.

Why do crystals grow faster in cold temperatures? Salt is more soluble in hot water than in cool . After the solution has come to room temperature, it is carefully set in an ice bath to complete the crystallization process. Put the pan on the stove and heat the sugar/water solution. Solution means a lot, not just watery solution, they can grow in a melt or in a superheated gas (to hot to stay liquid not matter how high the pressure).
