Product Description
24 Hole Magnesia Cupel Brick High Capacity Fire Assay Laboratory Gold Analysis
24 Hole Magnesia Cupel Brick for High Volume Fire Assay Gold and Silver Testing

The Y&X 24 hole cupel brick is built for the highest throughput fire assay laboratories. With 24 independent cup holes machined into one refractory brick, it processes up to 24 samples in a single cupellation run — the highest capacity in our cupel brick range, maximizing cupellation output per unit of furnace space.

24 Hole Magnesia Cupel Brick with 96% MgO Content for Fire Assay Gold Testing

Product Highlights
  • 96% high purity MgO formula with a special fluxing agent for superior absorption
  • Absorbs more than 70% of its own weight in lead oxide (PbO)
  • No cracking, pitting or lead spitting during cupellation
  • Each cavity performs identically to a single cupel, for batch consistency
  • One-piece brick body heats uniformly and reduces loading-position temperature deviation
  • Excellent thermal shock resistance, ready to use without pre-drying
  • Not affected by atmospheric humidity, no freezing tendency in any climate
  • Higher cupellation capacity per unit of furnace space
  • In-house laboratory quality testing with traceable batches
  • Custom cavity counts from 4 to 24 holes and custom packaging available
Maximum Throughput, Same Quality

Every cavity uses the same 96% high purity MgO base and sintering process as our single cupels, giving each position absorption behaviour identical to a single cupel. You scale up throughput without diluting quality.

Applications

Large gold mine assay laboratories, high volume commercial testing institutions and precious metal refineries that need standardized batch cupellation with maximum efficiency. Pairs well with a Y&X cupellation furnace for a complete batch cupellation workflow.

Y&X focuses on the fire assay analysis field and supplies a full range of high purity magnesia cupels and cupel bricks. Contact us for a quote or custom specification.

FAQ
Cupel or cupel brick — which should I choose?
 A cupel is a single round dish for small or individual samples; a cupel brick is a multi-cavity block that cupels many samples per run. Both use the same 96% magnesia material and work on the same principle. Under 20 samples per day, single cupels offer flexible pairing; for larger batches, a cupel brick is more efficient and provides a more uniform temperature field.
Do cupel bricks need pre-drying before use?
No. Cupel bricks can be placed directly into the cupellation furnace without pre-drying. The high purity magnesia formula gives excellent thermal shock resistance, so a brick at room temperature can enter the approximately 900°C working environment without cracking, saving preheating time and energy. If stored in extremely humid conditions (relative humidity above 85%), drying at 105°C for 2 hours before use is recommended.
How should cupel bricks be stored, and what is the shelf life?
They have low storage requirements; store them in a dry, ventilated place at room temperature. Unlike traditional bone-ash cupels, magnesia bricks are not affected by atmospheric humidity and will not freeze or degrade. Under proper storage they keep long term with unchanged performance, with a shelf life of more than 12 months under standard conditions.
