Add a seed crystal...(which does not have to be the same crystal as you try to precipitate..)


Or simply scratch the sides of the flask, The added crystal, or the scratch, serves as a so-called #"site of nucleation"#. A crystalline mass deposits. Note that the #"supersaturation"# defines a metastable, non-equilibrium condition. And the crystals that result from precipitation of a supersaturated solution are usually not first-class...
