CUPELLATION LABORATORY (FIRE ASSAYING)
The cupellation or fire assay method, classified under the norm UNI ISO 11426:2000, is an old and well known analytical methodology utilized for the determination of precious metals concentration.
The cupellation laboratory (fire assaying) consists of the following machines:
- Bench drill for sample taking
- Analytical balance for sample weighing with anti-vibration table
- Working bench for cupels treatment with rolling mill and annealing system
- Cupellation furnace with cartridge filter unit for removal of lead oxides
- Separation hood (parting hood) with fume scrubber
