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 250 x 250 x 500 MM chamber with usable chamber volume of 31.3 litre, approximate power load of 11.6 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.
A muffle furnace is usually the first furnace a lab installs, since it covers the broadest share of everyday heating, drying and ashing tasks before more specialised equipment is added.
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.
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.
