WebAt a high enough temperature, a solution can hold many minerals in suspension. As the temperature drops, the amount of solid ingredients it can hold in suspension drops as well. When that occurs, crystals form. In fact, different minerals in the same solution will crystallize at different temperatures. For example, corundum might crystallize first.
