The apparatus was mainly used for extracting minerals.
Procedure: This apparatus has a special furnace of angulas in width and one hasta (18”) in length and one hasta in height. Two Mushas (crucibles used in the laboratory) are taken, one of which has a lid with a hole. The Musha with the lid is filled with ore and is fixed upside down on the furnace, surrounding the upper Musha is filled with hard charcoal made of Bamboo, Khadira, Madhuka and Badari wood. A fire is light in the charcoal and has to keep raging, by blowing air with the help of bellows. Gradually the essence of the mineral gets collected in the lower pot.
