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.
This configuration is suitable when the sample load must fit a 810 x 450 x 450 MM chamber with usable chamber volume of 164 litre, approximate power load of 22.7 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.

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.
Where sample volume and process type vary week to week, a general-purpose muffle furnace avoids the cost of maintaining several process-specific furnace types.
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.
