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.
This configuration is suitable when the sample load must fit a 225 x 225 x 450 MM chamber with usable chamber volume of 22.8 litre, approximate power load of 10.2 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 1200 Degree Celsius (°C) Glass Heat Treatment Furnace 225 x 225 x 450 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.
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.
Routine QC and teaching labs value a muffle furnace precisely because one unit can cover several standard test methods without dedicated process-specific tooling.
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.
