Before any metal is cast, refined, or traded, it must be tested. In mining, mineral analysis is the gateway to value—and at the heart of that process lies heat. Whether you're running an assay lab or preparing samples for metallurgical evaluation, precision heating is what separates accurate results from costly guesswork.
Mineral testing isn’t just about identifying what’s in the ore—it’s about quantifying it with confidence. That means:
Stable furnace temperatures for repeatable results
Controlled heating zones to isolate reactions
Rapid thermal response to streamline workflows
Even slight temperature fluctuations can skew results, leading to misreported grades or inefficient downstream processing.
Our silicon carbide GLO-BARs are engineered for the exacting demands of mineral testing labs. Whether you're using muffle furnaces, crucible setups, or cupellation systems, our elements offer:
Consistent heat output from 1,300 °C to 1,600 °C
Chemical stability in oxidizing and reducing atmospheres
Custom geometries for tight furnace integration
Long service life to reduce lab downtime
From the GBU U Lit-Bar to the GBR Tornado, each element is built to maintain the thermal integrity your lab depends on.
Furn-Tek heating elements are trusted in:
Assay furnaces for gold, platinum, and base metal testing
Fluxing and cupellation setups for sample purification
Crucible furnaces for small-batch smelting and separation
Custom lab systems tailored to unique mineral profiles
Whether you're testing ore from a new prospect or verifying purity in refined metals, our products support every step of the process.
