This kiln uses electric heating elements to fire ceramic materials, offering clean and precise operation. Designed to reach at least 1000°C, it is the standard for modern studio potters and schools. The working principle involves coils or ribbons of Kanthal or silicon carbide elements embedded in refractory walls, controlled by a digital programmer. Its purpose is to bisque and glaze fire pottery and sculpture with excellent temperature uniformity and repeatability, without the need for fuel handling or flue management associated with gas kilns.
This configuration is suitable when the sample load must fit a 390 x 390 x 770 MM chamber with usable chamber volume of 117.1 litre, approximate power load of 19.8 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) Electric Ceramic Kiln 390 x 390 x 770 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.
