A variant of the Wohlwill electrolytic process, the Fizzer cell process is suitable for jewelers' small-scale refining operations. In the electrolytic cell, the cathode is contained within a porous ceramic pot, which acts as a semi-permeable membrane; it prevents gold dissolved in the electrolyte on the anode side of the wall from passing through and depositing on the cathode.
