This is the correct technical term for a furnace that fires porcelain ceramics to vitrification. Operating at temperatures near 1300°C, it is the final, high-fire step. The working principle requires precise control through the critical quartz inversion and vitrification ranges to achieve zero porosity and maximum strength without causing deformation or over-firing. Its purpose is to produce high-quality sanitaryware, electrical insulators, dental prosthetics, and fine art porcelain, where whiteness, translucency, and impermeability are defining characteristics.
This configuration is suitable when the sample load must fit a 860 x 435 x 435 MM chamber with usable chamber volume of 162.7 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.

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.
