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
