This furnace, or kiln, is used for firing stoneware clay, which vitrifies at high temperatures (around 1200°C) to become non-porous and very strong. The working principle involves a firing cycle that brings the clay to its maturation point, often in an oxidation or reduction atmosphere to affect clay and glaze colors. Its purpose is to produce durable pottery, dinnerware, and sanitaryware that is resistant to liquids and chipping. It is a staple in both studio pottery and industrial ceramic production for functional ware.
Trutherm manufactures 1400 Degree Celsius (°C) Stoneware Furnace 870 x 870 x 900 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.
This configuration is suitable when the sample load must fit a 870 x 870 x 900 MM chamber with usable chamber volume of 681.2 litre, approximate power load of 40.5 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.

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.
