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.
Trutherm manufactures 800 Degree Celsius (°C) Glass Fusing Furnace 125 x 125 x 250 MM Chamber for buyers who search by exact machine type, chamber size and 800°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 125 x 125 x 250 MM chamber with usable chamber volume of 4 litre, approximate power load of 5 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.

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.
