This furnace is part of a system used to purify silver, separating it from base metal impurities or other precious metals. Operating at temperatures around 1000°C, it may use processes like cupellation or electrolytic refining. The working principle in cupellation involves melting the impure silver with lead in an oxidizing atmosphere; lead and other impurities oxidize and are absorbed into a p...
This furnace is part of a system used to purify silver, separating it from base metal impurities or other precious metals. The working principle in cupellation involves melting the impure silver with lead in an oxidizing atmosphere; lead and other impurities oxidize and are absorbed into a porous cupel, leaving pure silver behind. Operating at temperatures around 1000°C, it may use processes like cupellation or electrolytic refining. The Silver Refining Furnace is available in 5 temperature configurations ranging from 1000°C to 1400°C. Each temperature variant is engineered with appropriate thermocouple and heating element technology.
