This furnace is designed for melting or fusing glass to create beads or other small glass items. Operating at temperatures around 800°C, it heats glass to a viscous state suitable for shaping. The working principle typically involves a small, concentrated heating zone, often using a torch-like flame or an electric element in a bench-top design, allowing an artisan to manipulate the glass. Its purpose is for crafting decorative glass beads, scientific glassware components, or small artistic pieces. It is a fundamental tool in glass art studios and specialized glassworking shops, enabling detailed handcrafting.
This configuration is suitable when the sample load must fit a 275 x 540 x 275 MM chamber with usable chamber volume of 40.8 litre, approximate power load of 12.9 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.

Trutherm manufactures 800 Degree Celsius (°C) Bead Furnace 275 x 540 x 275 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.
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.
