This furnace (kiln) is used for firing terracotta, a porous, red-brown earthenware clay. Operating at moderate temperatures (around 900°C), it hardens the clay without causing vitrification. The working principle is a standard bisque firing cycle, driving off water and organic matter and sintering the clay particles enough for strength while maintaining porosity. Its purpose is for producing terracotta flower pots, architectural tiles, sculptures, and decorative items. The distinctive color comes from the iron content in the clay, which oxidizes to red during firing.

Trutherm manufactures 1200 Degree Celsius (°C) Terracotta Furnace 630 x 630 x 890 MM Chamber for buyers who search by exact machine type, chamber size and 1200°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 630 x 630 x 890 MM chamber with usable chamber volume of 353.2 litre, approximate power load of 31 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.
Routine QC and teaching labs value a muffle furnace precisely because one unit can cover several standard test methods without dedicated process-specific tooling.
Uniform chamber heating and a simple door-loading design make a muffle furnace straightforward to standardise across multiple operators and shifts.
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.
