This kiln is defined by its enclosed, chamber-like structure for firing ceramics, enamel, or glass. Operating temperatures start around 900°C. The working principle is similar to a chamber furnace but is optimized for ceramic cycles, often with provisions for placing ware on shelves and managing combustion gases or glaze vapors. Its purpose is to provide a controlled, reproducible environment for both bisque and glaze firings in studio, educational, or industrial settings. It is one of the most common kiln designs due to its efficiency and even heat distribution.

Trutherm manufactures 900 Degree Celsius (°C) Chamber Kiln 870 x 435 x 435 MM Chamber for buyers who search by exact machine type, chamber size and 900°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 435 x 435 MM chamber with usable chamber volume of 164.6 litre, approximate power load of 22.8 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 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.
