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 1200 Degree Celsius (1200°C) Bead Kiln 330 x 330 x 650 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.
This configuration is suitable when the sample load must fit a 330 x 330 x 650 MM chamber with usable chamber volume of 70.8 litre, approximate power load of 16.2 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.

Routine QC and teaching labs value a muffle furnace precisely because one unit can cover several standard test methods without dedicated process-specific tooling.
Uniform chamber heating and a simple door-loading design make a muffle furnace straightforward to standardise across multiple operators and shifts.
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.
