Functionally identical to the Gem Heat Treatment Furnace, this unit thermally enhances gemstones. Operating around 600°C, its purpose is to diffuse impurities, heal fractures, or change color centers through controlled heating. The working principle requires extremely stable temperature control and often operates in batches. It is a key piece of capital equipment for gemstone wholesalers and treatment facilities, allowing them to consistently upgrade rough or low-grade gem material to meet market demands for color and clarity.

Trutherm manufactures 600 Degree Celsius (°C) Gemstone Heat Treatment Furnace 870 x 760 x 760 MM Chamber for buyers who search by exact machine type, chamber size and 600°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 760 x 760 MM chamber with usable chamber volume of 502.5 litre, approximate power load of 35.8 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.
A muffle furnace is usually the first furnace a lab installs, since it covers the broadest share of everyday heating, drying and ashing tasks before more specialised equipment is added.
A muffle furnace isolates the sample from direct contact with heating elements or combustion gases, giving cleaner, more repeatable results than an open flame or hot-plate process.
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.
