Crystallization of a solution of ammonium aluminium sulfate dodecahydrate by cooling and by vacuum evaporation was performed in a laboratory batch experiment. In the two crystallization modes, the nucleation was found to proceed at different rates whereas the crystal growth rate did not differ significantly.
