Synonymous with the Biscuit Firing Furnace, this kiln performs the crucial first firing of ceramic objects. Operating at approximately 900°C, it permanently hardens the clay through sintering of particles. The working principle requires careful control of the heating rate, especially through the quartz inversion and dehydration stages, to ensure even heating and avoid thermal shock. Its purpose is to produce a robust, absorbent bisqueware ready for glazing. This process is universal in ceramic arts and industrial pottery, setting the foundation for the final glazed product's strength and quality.
Trutherm manufactures 1000 Degree Celsius (°C) Bisque Firing Furnace 450 x 450 x 600 MM Chamber for buyers who search by exact machine type, chamber size and 1000°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 450 x 450 x 600 MM chamber with usable chamber volume of 121.5 litre, approximate power load of 20.1 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.

Routine QC and teaching labs value a muffle furnace precisely because one unit can cover several standard test methods without dedicated process-specific tooling.
Uniform chamber heating and a simple door-loading design make a muffle furnace straightforward to standardise across multiple operators and shifts.
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.
