Specifically designed for firing clay-based ceramics, this kiln handles the specific thermal requirements of clay bodies from earthenware to stoneware. Capable of reaching at least 1000°C, it drives the sintering process that turns soft clay into hard ceramic. The working principle involves careful programming to manage dehydration, quartz inversion, and vitrification stages critical to clay transformation. Its purpose is the heart of pottery and brick/tile manufacturing, determining the final strength, porosity, and aesthetic of the product. It ranges from small electric hobby kilns to large tunnel kilns for industrial production.
Trutherm manufactures 800 Degree Celsius (°C) Clay Kiln 390 x 390 x 770 MM Chamber for buyers who search by exact machine type, chamber size and 800°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 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.

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.
