This is a purely electrolytic system, requiring a separate rectifier (available from Shor) and works only with silver that is at least 90% pure before refining (Sterling silver is 92+% pure). Produces standard electrolytic grade silver of 99.95-99.99% purity. Uses a dilute nitric acid for electrolyte, so some ventilation is required. Requires a rectifier of at least 25 amps (not included).
