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 1100 Degree Celsius (°C) Bisque Firing Furnace 900 x 870 x 870 MM Chamber for buyers who search by exact machine type, chamber size and 1100°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 900 x 870 x 870 MM chamber with usable chamber volume of 681.2 litre, approximate power load of 40.5 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.
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.
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.
