This kiln is specifically engineered for creating glass beads through processes like lampworking or fusing. Operating at similar temperatures to the bead furnace (around 800°C), it is used for the final annealing or fusing stage. The working principle involves a chamber that heats multiple beads uniformly and slowly to relieve stresses introduced during shaping, then cools them under controlled conditions. Its purpose is to ensure the durability and stability of the finished glass beads by preventing internal fractures. Popular among jewelry makers and glass artists, it is an essential piece of equipment for producing high-quality, durable beadwork.

This configuration is suitable when the sample load must fit a 575 x 575 x 900 MM chamber with usable chamber volume of 297.6 litre, approximate power load of 28.9 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 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.
