The Rasaratna Samuccaya of Vāgbhat states that a gold leaf of the weight of one karshā is to be smeared with Saimndhava salt and placed between two' earthen saucers and heated on a charcoal fire for an hour and a half, when its true colour will come out. 1; li..."
Gold can be reduced to ashes with the aid of the ashes of mercury, through the agency of the roots of plant, and with Sulphur. The first process is the best, the second medium and the third lowest or least.?
Gold leaves, pierced with holes and coated with a pastle of lemon juice and the ashes of mercury and roasted ten times are thereby killed. 3
