About This 1200°C Silver Refining Furnace 490 x 490 x 870 MM Chamber
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 porous cupel, leaving pure silver behind. Its purpose is to produce fine silver (99.9%+ pure) from scrap, coins, or mined bullion for industrial, investment, and artistic uses.

Why Choose This Silver Refining Furnace
As a general-purpose muffle furnace, this model covers a broader range of routine heating tasks than a process-specific ashing, tube or sintering furnace, making it the practical default when the lab runs mixed sample types rather than one dedicated process.
