This furnace is part of a system used to purify gold, separating it from other metals and impurities. Operating at temperatures around 1100°C, it facilitates chemical reactions like chlorination or the Miller process. The working principle involves melting the impure gold with specific fluxes or bubbling chlorine gas through the melt, causing impurities to form a slag or fume off. Its purpose is to produce high-purity (99.9%+) gold from scrap, ore, or doré. It is central to precious metal refineries and recycling operations.

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.
