    FAC7A Fire Assay Cupel Size 7A - Almath Crucibles Ltd.
    7A Fire Assay Cupels (7AL) are high-purity magnesia (MgO) or bone ash, tapered ceramic vessels used in laboratories for cupellation to separate precious metals from lead and impurities. These specific cupels generally feature a 1-9/16" diameter, are designed to absorb up to
    41.7
    g
     of lead, and offer high thermal shock resistance and a
    97
    %
    −98.5
    %
     recovery rate. 
    Key Features & Specifications 
    • Material: High-purity Magnesia (MgO) or bone ash.
    • Capacity: Standard 7A size (often 1-9/16" top diameter) capable of absorbing 41.7 grams of lead, ideal for 1 Assay Ton (AT) or smaller loads.
    • Design: Tapered exterior, thick base, and hemispherical interior to prevent metal loss and improve handling.
    • Performance: Rapid absorption, high refractoriness, and stability at cupellation temperatures (
      >850∘Cis greater than 850 raised to the composed with power C
      >850∘C
      ).
    • Application: Widely used for gold/silver assaying, refining, and testing in mining and laboratory settings. 
    7A cupels are known for being a best-seller for fire assaying, providing reliable, consistent performance with minimal metal retention, often used for precision analysis in precious metal labs.

    How does fire test the purity of gold?
    Fire assaying is the best way to determine what the purity of gold is. But many do not know what it is or how it works. Fire Assay is a qualitative determination in which gold is separated from impurities by fusion processes and weighed to determine the actual amount of gold present in the original sample.Feb 19, 2010
