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.
This configuration is suitable when the sample load must fit a 225 x 225 x 450 MM chamber with usable chamber volume of 22.8 litre, approximate power load of 10.2 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 is usually the first furnace a lab installs, since it covers the broadest share of everyday heating, drying and ashing tasks before more specialised equipment is added.
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.
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.
