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.
This configuration is suitable when the sample load must fit a 190 x 190 x 360 MM chamber with usable chamber volume of 13 litre, approximate power load of 8.1 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 1300 Degree Celsius (°C) Glass Softening Furnace 190 x 190 x 360 MM Chamber for buyers who search by exact machine type, chamber size and 1300°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.
