This furnace thermally tempers glass by heating it to its softening point (around 650°C) and then rapidly quenching it with high-pressure air blasts. This process puts the surface into compression and the core into tension. The working principle involves a horizontal or vertical chamber where glass sheets are heated uniformly and then moved to a quench section within seconds. Its purpose is to produce safety glass that is 4-5 times stronger than annealed glass and breaks into small, relatively harmless granules. It is mandatory for glass in doors, shower enclosures, and automotive side windows.
This configuration is suitable when the sample load must fit a 800 x 885 x 800 MM chamber with usable chamber volume of 566.4 litre, approximate power load of 37.6 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.

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.
