Cooling causes crystals of silver nitrate to develop, much like salt crystals in water. The crystals are faraway from the answer and whirled in centrifuges with sieve-like openings to take away the water and maintain the crystals pure. At this level within the course of, the chemical options are light-delicate, so further manufacturing processes are accomplished in darkness.
