This kiln or furnace is designed for fusing multiple layers of glass together into a single piece. Operating at fusing temperatures (around 800°C), it heats compatible glass sheets or pieces until they bond. The working principle requires a very flat heating chamber to prevent slumping and precise control to hold at specific temperatures for tack fusing, full fusing, or slumping into molds. Its purpose is central to the creation of fused glass art, jewelry, and architectural glass features. It allows for intricate designs by layering colored glass.
This configuration is suitable when the sample load must fit a 390 x 390 x 770 MM chamber with usable chamber volume of 117.1 litre, approximate power load of 19.8 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.

Trutherm manufactures 1200 Degree Celsius (°C) Glass Fusing Furnace 390 x 390 x 770 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.
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.
