Precision for Reliable Assaying

Each magnesia cupel is engineered using high-purity MgO with minor CaO and SiO, ensuring consistent, reliable performance in precious metal analysis. Manufactured with advanced moulding and sintering processes, these cupels maintain structural integrity and high cold crushing strength, providing exceptional results in fire assaying environments.

Optimized Design for Laboratory Use

Featuring excellent resistance to thermal shock and a low thermal conductivity, these cupels are ideal for rigorous laboratory operations. Their smooth surface, dense structure, and optimized porosity promote efficient absorption of lead oxide. The off-white to greyish-white color assists with visual monitoring during assays.

Long-Lasting and Easy to Store

These cupels offer a long shelf life when kept in cool, dry conditions as recommended. Their robust construction and high hardness mean they endure repeated exposure to high temperatures without compromising dimensional stability, supporting cost-effective laboratory operations and reliable results over time.

FAQs of 9 Magnesia Cupels:

Q: How should I store magnesia cupels to maximize their shelf life?

A: Store magnesia cupels in a cool, dry environment away from moisture and contaminants. Proper storage helps maintain their high hardness and structural integrity, ensuring a long shelf life and optimal performance during use.

Q: What is the recommended usage process for these cupels in fire assaying?

A: Place the magnesia cupel in your standard cupellation furnace, typically heated up to 1700C. Add the sample with lead, allowing the optimized porosity to absorb lead oxide efficiently, leaving behind gold or silver for analysis.

Q: When should these cupels be replaced during laboratory operations?

A: Replace a cupel after each use, especially when conducting precious metal assays, to prevent cross-contamination and maintain analytical accuracy. Their low water absorption and high cold crushing strength ensure reliability for single-use applications.

Q: What are the main benefits of using magnesia cupels over other types?

A: Magnesia cupels offer excellent resistance to thermal shock, dimensional stability at high temperatures, and superior absorption of lead oxide. These advantages enhance the precision of fire assaying and minimize the risk of cupel failure during critical processes.

Q: Where are these magnesia cupels typically utilized?

A: They are primarily used in laboratories, refining industries, and for precious metal analysis, including gold and silver assaying. Their compatibility with most standard cupellation furnaces makes them suitable for a wide range of professional settings.

Q: What makes the manufacturing process of these cupels distinct?

A: The cupels are precision-moulded and sintered with high-purity magnesia, resulting in a dense, smooth, and robust structure. This advanced process ensures consistent quality and high strength for demanding assaying tasks.
