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.
Trutherm manufactures 1300 Degree Celsius (°C) Porcelain Firing Furnace 90 x 110 x 115 MM Chamber for buyers who search by exact machine type, chamber size and 1300°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 90 x 110 x 115 MM chamber with usable chamber volume of 1.1 litre, approximate power load of 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.

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.
Routine QC and teaching labs value a muffle furnace precisely because one unit can cover several standard test methods without dedicated process-specific tooling.
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.
