Custom Fire Assay Solution：September 2025 — Leveraging years of specialized expertise in fire assay laboratory instrumentation, Qingdao Decent Group has successfully delivered and commissioned a fully custom fire assay solution for a leading precious metals testing facility in Singapore. This turnkey project included the design, manufacturing, installation, and commissioning of precision fusion and cupellation furnaces—showcasing China’s rising capabilities in high-end scientific equipment and reinforcing Decent Group’s position as a trusted global supplier.
Delivery Step One: Accurately Understanding Customer Needs
Fire assay remains the gold standard for accurate precious metals analysis, particularly for gold and silver content determination in ores, metals, and alloys. As a major Asia-Pacific precious metals trading hub, Singapore imposes stringent technical and quality requirements on fire assay equipment.
The client, a mineral and precious metals analysis specialist, faced challenges such as aging equipment, inefficient processing, and cumbersome consumable replacement. They needed a custom fire assay solution with precision, operational stability and user-friendly maintenance as top priorities.
Custom Fire Assay Solution: Precision-Built Fire Assay Equipment
Based on customer needs, our technical team designed a set of fire assay equipment solutions that meet the requirements, including a customized melting furnace and ash blowing furnace. During the design process, the team fully considered the unique requirements of the fire assay process and the scale and processes of the customer’s laboratory to ensure that the equipment matches the scale of the customer’s laboratory and the number of samples processed.
DECENT Fusion Furnace
During fire assay, sample fusion serves as the foundational step where the ore is fused with flux at elevated temperatures to isolate precious metals within a molten lead prill. Sample melting is a critical step in fire assaying, crucial for the accuracy of the test results. Prepared samples and flux are melted in a furnace to form metal particles containing precious metals.
- DECENT fusion furnace can reach temperatures up to 1,200°C with an accuracy of ±1° Silicon carbide heating elements ensure uniform and stable heating, and are available in a variety of sizes.
- Modular refractory chamber design enables quick replacement and extends silicon carbide heating element life
- Robust 2mm galvanized steel housing ensures corrosion resistance and structural integrity
DECENT Cupellation Furnace
The importance of the cupellation process cannot be ignored. It mainly involves placing the metal particles obtained after melting the sample into a cupellation furnace and heating it. Controlled by air flow and other factors, the cupellation furnace separates precious metals like gold and silver from impurities, leaving behind gold and silver beads in the ash dish. This step requires accurate endpoint determination, which significantly impacts the final results.
- Customizable capacity (50/100/168-cupel configurations) to match batch processing needs
- Integrated fume extraction system safely manages hazardous gases during cupellation
- High-performance silicon carbide elements (1,200°C max) with protective chamber for uniform, stable heating

On-site Implementation: Professional Installation and Detailed Commissioning
Following the safe arrival of equipment at the client’s Singapore laboratory, DECENT engineering team promptly deployed on-site. Accounting for the lab’s specific spatial constraints, the team strategically positioned the equipment to:
- Maintain optimal workflow integration with the existing layout
- Ensure seamless connectivity to power and ventilation systems
- Upon installation completion, the team conducted rigorous performance validation through simulated operational runs.
Key focus areas included:
- Real-time monitoring of furnace heating ramp rates
- Verification of temperature profile stability across operational cycles
- Confirmation that all parameters met stringent specification requirements
- Hands-on training sessions were then delivered, covering:
- Standard operating procedures with live equipment demonstrations
- Proactive maintenance protocols to maximize uptime
- Step-by-step troubleshooting for typical operational scenarios
