A kiln specifically designed for the high-temperature firing of stoneware pottery. Operating at temperatures near 1200°C, it must sustain the heat long enough for the clay to fully vitrify. The working principle for studio potters often involves electric or gas kilns with heavy insulation. Its purpose is to create the classic, sturdy pottery known as stoneware, which ranges from rustic cookware to refined tableware. The kiln atmosphere (oxidizing or reducing) is carefully managed to develop the characteristic colors and textures of glazes used on stoneware.
This configuration is suitable when the sample load must fit a 450 x 450 x 450 MM chamber with usable chamber volume of 91.1 litre, approximate power load of 17.9 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.
