Hobersal cupellation furnace is a type of furnace that is used to purify precious metals such as gold and silver. The process of cupellation involves heating the metal in a shallow, porous vessel called a cupel, along with a substance such as lead that oxidizes any impurities in the metal.

Hobersal cupellation furnace is designed to provide a controlled environment for this process. The furnace typically consists of a muffle, which is a sealed chamber made of refractory materials that can withstand high temperatures. The muffle contains the cupels and the metal being purified.

The furnace is heated to a high temperature, typically between 900 and 1000 degrees Celsius, which causes the metal to melt and the impurities to oxidize and vaporize. The gases released by this process are drawn off by a fume hood or chimney.

The cupellation process is used in the refining of precious metals, and the resulting metal is often used in jewelry, electronics, and other high-tech applications.
