A kiln specifically for firing terracotta pottery. Operating at temperatures like 900°C, it is typically an oxidation firing (with ample air) to produce the classic red color. The working principle is straightforward, often using electric or simple updraft gas designs. Its purpose is central to industries producing construction materials (roof tiles, bricks) and decorative arts. It represents one of the oldest and most widespread forms of ceramic firing, as terracotta's relatively low firing temperature makes it accessible and economical.
This configuration is suitable when the sample load must fit a 680 x 400 x 400 MM chamber with usable chamber volume of 108.8 litre, approximate power load of 19.2 kW, rectangular - wide 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.

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.
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.
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.
