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.

Trutherm manufactures 1400 Degree Celsius (1400°C) Bead Kiln 390 x 390 x 770 MM Chamber for buyers who search by exact machine type, chamber size and 1400°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.
This configuration is suitable when the sample load must fit a 390 x 390 x 770 MM chamber with usable chamber volume of 117.1 litre, approximate power load of 19.8 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.
Uniform chamber heating and a simple door-loading design make a muffle furnace straightforward to standardise across multiple operators and shifts.
Where sample volume and process type vary week to week, a general-purpose muffle furnace avoids the cost of maintaining several process-specific furnace types.
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.
