Specifically designed for melting pure gold, this furnace reaches the high temperature (1150°C+) needed to liquefy the precious metal. It prioritizes minimal metal loss. The working principle commonly uses a graphite or clay crucible within an induction coil or resistance-heated chamber, often with a tilt mechanism for precise pouring. Its purpose is for refining, recycling, and casting gold into bars, ingots, or investment cast jewelry components. In jewelry shops and refineries, it is a critical tool for handling high-value material efficiently.
Trutherm manufactures 1200 Degree Celsius (°C) Gold Melting Furnace 870 x 790 x 790 MM Chamber for buyers who search by exact machine type, chamber size and 1200°C temperature rating. This page is specific to the MM dimension version, so the chamber size is presented in the unit normally used in the buyer's drawing, tender or purchase request.
This configuration is suitable when the sample load must fit a 870 x 790 x 790 MM chamber with usable chamber volume of 543 litre, approximate power load of 36.9 kW, rectangular - wide chamber profile. It is commonly selected for laboratory, QC, metallurgical, ceramic, pharmaceutical and industrial heat-treatment work requiring stable heating and repeatable process conditions. Typical use includes general laboratory and industrial heat-treatment applications requiring stable, repeatable temperature control.

Routine QC and teaching labs value a muffle furnace precisely because one unit can cover several standard test methods without dedicated process-specific tooling.
Uniform chamber heating and a simple door-loading design make a muffle furnace straightforward to standardise across multiple operators and shifts.
As a general-purpose muffle furnace, this model covers a broader range of routine heating tasks than a process-specific ashing, tube or sintering furnace, making it the practical default when the lab runs mixed sample types rather than one dedicated process.
