This furnace performs various thermal processes on glass, including annealing, tempering (thermal strengthening), and bending. Operating at temperatures like 650°C, it heats the glass uniformly to a specific point before the next step (like quenching for tempering). The working principle depends on the process: for tempering, it involves rapid, uniform air quenching; for annealing, controlled slow cooling. Its purpose is to enhance the mechanical and safety properties of glass for applications ranging from automobile windshields and building windows to smartphone screens.

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.
