An industry term for the kiln used in "glost firing," the final firing of already-glazed pottery. Operating around 1000°C, its sole purpose is to mature the glaze. The working principle is similar to a glazing furnace but is often used in a production line context where bisque ware from a biscuit kiln is glazed and then transferred to the glost kiln. It is engineered for efficiency and consistency in large-scale tableware and sanitaryware manufacturing, where thousands of pieces are fired at once.
This configuration is suitable when the sample load must fit a 640 x 340 x 340 MM chamber with usable chamber volume of 74 litre, approximate power load of 16.5 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.

Trutherm manufactures 1300 Degree Celsius (°C) Glost Furnace 640 x 340 x 340 MM Chamber for buyers who search by exact machine type, chamber size and 1300°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.
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.
Because muffle furnaces are used across ashing, drying, calcination and light heat-treatment, the chamber and controller are specified for flexibility rather than one narrow process window.
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.
