At Mechelec, we understand the importance of precision in gold and silver analysis. Fire assay remains the most reliable method for testing the purity of precious metals. This traditional technique depends heavily on the quality of tools used. In this guide, we highlight all the fire assay equipment you’ll need and how Mechelec’s range ensures consistent and accurate results.

What Is Fire Assay?

Fire assay is a high-temperature process that determines the content of precious metals in a sample. It involves three primary stages: fusion, cupellation, and parting. Each step demands equipment that can handle extreme heat and chemical reactions. That’s where Mechelec comes in.

Core Fire Assay Equipment from Mechelec

1. Crucibles

Our graphite crucibles and induction crucibles are engineered for high thermal conductivity and shock resistance. They come in various capacities—500 gm to 12 kg—making them suitable for everything from lab-scale to industrial operations.

2. Cupels

Mechelec offers bone ash and magnesia-based cupels designed to absorb lead oxide efficiently during the cupellation process. You can find standard sizes like Cupel 1, Cupel 6HB Leg, PM Cupel, and more.

3. Fire Assay Furnaces

Our cupellation furnaces are built for consistent performance. Choose from small and large annealing furnaces or our durable melting furnaces, depending on your throughput needs. Each furnace is optimised for energy efficiency and high thermal stability.

4. Parting Trays

We manufacture parting trays with 12, 16, 25, and 36 holes. These are used in the nitric acid parting stage to separate gold from silver. Their acid-resistant material ensures safe and long-lasting use.

5. Tongs and Tools

Proper handling is critical in high-temperature environments. Mechelec supplies crucible tongs, steel parting tray tongs, and cupel tongs—all designed to provide safety and grip during operation.

6. Muffles

Our SiC muffles are essential for providing uniform heat distribution within furnaces. Made of high-grade silicon carbide, they ensure prolonged life and energy-efficient operation.

7. Accessories

Mechelec also provides glass stirrer rods, laboratory tongs, aprons, and thermocouples to complete your fire assay setup.
