Precious metals models >> Cupellation (fire assay) furnaces (CF)

Cupellation (fire assay) furnaces (CF) for the precious metals market


 
  • The assay of gold alloys by cupellation is the standard method used by the United Kingdom Assay Offices and a reference laid down by the International Hallmarking Convention
  • Comply with ISO 11426 : 1999
  • The Carbolite range of fire assay and cupellation furnaces has an international reputation for close temperature uniformity, low heat loss and maximum fume control
  • Maximum operating temperature 1200°C
  • One bench mounted and three floor standing models, with capacities ranging from 15 x cupel #8 up to 90 x cupel #6
  • Silicon carbide heating elements are mounted above and below the work chamber, providing even heating of the cupels
  • Fumes are extracted through an insulated exhaust duct and a removable container, situated below the chimney, collects any condensed lead
  • Incoming air, which is controlled by an adjustable valve at the rear of the furnace, is preheated by passing over the lower elements prior to entering the chamber - ensuring rapid heat transfer and even temperature distribution
  • The work chamber, roof and hearth are lined with silicon carbide tiles which will withstand the corrosive lead fumes emitted during the process
