Separating a soluble solid from a liquid

Evaporation can remove solvent from a solution, leading to the production of a saturated solution. Crystallisation reforms a solute as crystals from a saturated solution following a change in conditions. Solvents evaporate into the air around you during the process of crystallisation. Larger crystals form when the solvent evaporates more slowly. Heating a solution makes the solvent evaporate more quickly.
