This furnace is used for fusing vitreous enamel (a powdered glass) onto metal surfaces to create a durable, decorative, and protective coating. Operating around 800°C, it heats the metal until the enamel powder melts and flows. The working principle involves a chamber that heats the piece evenly to avoid thermal shock, which can crack the enamel. Its purpose is in manufacturing enameled cookware, signage, jewelry, and architectural panels. It requires precise temperature control to achieve a smooth, glossy finish without burning the colors.
Trutherm manufactures 1100 Degree Celsius (1100°C) Enamel Furnace 690 x 890 x 690 MM Chamber for buyers who search by exact machine type, chamber size and 1100°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 690 x 890 x 690 MM chamber with usable chamber volume of 423.7 litre, approximate power load of 33.4 kW, rectangular - tall 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.

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.
Routine QC and teaching labs value a muffle furnace precisely because one unit can cover several standard test methods without dedicated process-specific tooling.
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.
