Superior Material and Durability

Crafted from magnesia (MgO) with minor additives, our cupels offer high purity and exceptional thermal stability. Their robust structure endures prolonged high-temperature use with remarkable resistance to heat shock, while their low porosity and moisture content reduce contamination and guarantee reliable results in gold and silver assays.

Efficient and Precise Assaying

With efficient lead absorption and controlled ash content, these cupels ensure accurate analysis and minimal loss of precious metals during the fire assay process. Their smooth finish and consistent density foster uniform results, supporting laboratories, manufacturers, and exporters engaged in precious metal testing.

Flexible Packaging and Prompt Delivery

Available shrink-wrapped or in sturdy cardboard boxes, our cupels arrive protected and ready for immediate use. Standard orders ship within 12 weeks, with flexibility for custom sizes to match unique laboratory requirements. Proper storage guarantees a lengthy shelf life, supporting inventory management for distributors and wholesalers.

FAQs of 10 Magnesia Cupels:

Q: How should Magnesia Cupels be stored to maintain their shelf life?

A: Store the magnesia cupels in a dry, moisture-free environment to ensure their longevity. Keeping them away from humidity and contaminants preserves their structural integrity and absorption capacity.

Q: What is the recommended process for using these cupels in gold and silver assaying?

A: Place the sample with lead in the cupel and subject it to high temperatures above 1,500C. The cupel efficiently absorbs lead, allowing the precious metals to remain for accurate analysis.

Q: When will my standard order of Magnesia Cupels be delivered?

A: Standard orders are typically processed and shipped within 1 to 2 weeks after confirmation. Custom size requests may require additional lead time.

Q: Where are these magnesia cupels commonly used?

A: They are widely used in laboratories, refineries, and precious metal analysis facilities for gold and silver fire assay processes, both in India and internationally.

Q: What benefits do Magnesia Cupels offer over other cupel materials?

A: Magnesia cupels provide high purity, superior resistance to heat shock, controlled porosity for efficient lead absorption, and excellent dimensional stability at high temperatures, resulting in accurate and consistent assaying outcomes.

Q: How does the isostatic pressing and sintering process enhance cupel quality?

A: Isostatic pressing uniformly compacts the material, eliminating voids and promoting strength, while sintering further consolidates the structure, resulting in robust, dense, and reliable cupels.
