Specifically designed for melting pure gold, this furnace reaches the high temperature (1150°C+) needed to liquefy the precious metal. It prioritizes minimal metal loss. The working principle commonly uses a graphite or clay crucible within an induction coil or resistance-heated chamber, often with a tilt mechanism for precise pouring. Its purpose is for refining, recycling, and casting gold into bars, ingots, or investment cast jewelry components. In jewelry shops and refineries, it is a critical tool for handling high-value material efficiently.

A muffle furnace is usually the first furnace a lab installs, since it covers the broadest share of everyday heating, drying and ashing tasks before more specialised equipment is added.
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.
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.
