This is a kiln that incorporates a muffle—an inner liner or box that separates the ware from the direct flames or combustion products. Operating up to 1000°C, it provides a clean firing environment. The working principle protects delicate glazes or materials from contamination by sulfur or other compounds in the fuel. Its purpose is historically significant for firing porcelain and fine ceramics where pure colors were essential; today, it's used for high-value technical ceramics, enameling, and glass fusing where absolute control over the atmosphere around the workpiece is required.

Trutherm manufactures 900 Degree Celsius (°C) Muffle Kiln 765 x 890 x 765 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 765 x 890 x 765 MM chamber with usable chamber volume of 520.9 litre, approximate power load of 36.3 kW, rectangular - tall 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.
Uniform chamber heating and a simple door-loading design make a muffle furnace straightforward to standardise across multiple operators and shifts.
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.
