Specifically designed for melting pure silver (melting point 961°C), this furnace operates at temperatures like 1050°C. It is engineered for efficiency and minimal oxidation loss. The working principle typically uses a graphite or clay crucible in an electric resistance or induction furnace. Its purpose is for refining, recycling, and casting silver into bars, grain, or custom shapes for investment casting. In jewelry and silversmithing workshops, it is a fundamental tool for preparing metal for fabrication.
This configuration is suitable when the sample load must fit a 820 x 820 x 870 MM chamber with usable chamber volume of 585 litre, approximate power load of 38.1 kW, square 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.

Trutherm manufactures 1200 Degree Celsius (°C) Silver Melting Furnace 820 x 820 x 870 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.
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.
Because muffle furnaces are used across ashing, drying, calcination and light heat-treatment, the chamber and controller are specified for flexibility rather than one narrow process window.
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.
