    Mabor Magnesia Cupel Block 12HB - Microcupellation ...
    Magnesia (MgO) cupels are high-quality, durable, and porous refractory containers used in fire assaying to separate precious metals from lead, withsize 12 cupels capable of absorbing large quantities of litharge (
    PbOcap P b cap O
    𝑃𝑏𝑂
    ), typically around 354 grams, making them ideal for high-lead assays. They offer high, uniform absorption, low precious metal loss, and resistance to spitting. 
    Key Features & Properties of 12 MgO Cupels 
    • Material: Made from dead-burnt Magnesium Oxide (MgO), providing a robust, stable structure that resists cracking and pitting. 
    • Capacity: Size 12 cupels often feature large capacities, specifically designed for high absorption, with some models absorbing over 350 grams of lead. 
    • Performance: Mabor-type Magnesia cupels allow for rapid absorption of litharge (
      PbOcap P b cap O
      𝑃𝑏𝑂
      ) and prevent freezing at the end of the cupellation process.       
    • Dimensions: A common size 12 Mabor cupel, such as the one available from A&B Prospecting or in this item listing, has a large dimension suited for large lead buttons, often over 3 inches in diameter. 
    • Usage: Used in an oxidizing atmosphere in a furnace, typically at temperatures between 900-1000°C. 
    Magnesia cupels are generally more robust than traditional bone ash cupels and are preferred for their consistent, low-loss performance. For more specialized, smaller-scale applications, you can also explore microcupellation blocks from Fire Assay.
