This furnace heats glass to its softening point (around 750°C), where it becomes viscous enough to be shaped or slumped under gravity. It is used for processes like glass slumping into molds or drape forming. The working principle involves a chamber that heats the glass evenly until it softens and slowly sags to conform to a mold's shape below it. Its purpose is in artistic glassworking and industrial production of shaped glass components, such as glass sinks, lighting fixtures, and decorative panels. Careful control prevents overheating and loss of form.

Trutherm manufactures 1200 Degree Celsius (°C) Glass Softening Furnace 900 x 900 x 900 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.
This configuration is suitable when the sample load must fit a 900 x 900 x 900 MM chamber with usable chamber volume of 760 litre, approximate power load of 41.6 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.
Uniform chamber heating and a simple door-loading design make a muffle furnace straightforward to standardise across multiple operators and shifts.
Where sample volume and process type vary week to week, a general-purpose muffle furnace avoids the cost of maintaining several process-specific furnace types.
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.
