This furnace, also called a bisque firing kiln, conducts the initial firing of ceramic ware to transform shaped clay into a durable, porous bisque. Operating around 900°C, it drives off physical and chemical water and begins vitrification. The working principle involves a controlled ramp-up of temperature to prevent steam pressure from cracking the ware, followed by a soak period and controlled cooling. Its purpose is to harden the clay body so it can withstand handling and the absorption of liquid glaze before the final firing. It is a fundamental first step in all professional and studio pottery production.
This configuration is suitable when the sample load must fit a 170 x 230 x 240 MM chamber with usable chamber volume of 9.4 litre, approximate power load of 7.1 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.

Trutherm manufactures 1400 Degree Celsius (°C) Biscuit Firing Furnace 170 x 230 x 240 MM Chamber for buyers who search by exact machine type, chamber size and 1400°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.
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.
