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.
This configuration is suitable when the sample load must fit a 300 x 300 x 450 MM chamber with usable chamber volume of 40.5 litre, approximate power load of 12.9 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.

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.
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.
