Here, the lead amalgam (nāgarāji) is ordinary, having small efficacy. / The chalcopyrite amalgam (mākṣikārāji) has middling efficacy. / The bell-metal amalgam (vyoṣarāji) is superior, having great efficacy. / The ayaḥprakāśa amalgam is superior to all those amalgams, meaning it produces the best results of all. / Therefore, the ayaḥprakāśa amalgam is stated first. / One pala of tempered steel and two palas of bell-metal; / nine palas of pure copper and three palas of brass; / fifteen palas of lead killed with realgar: / throwing thirty palas in total into a crucible, they should be melted. / Then, taking seven and a half palas of golden chalcopyrite and casting it gradually into the middle, it should be melted gently again and again until it equals the measure of the copper part. / This is the meaning: / there are nine palas of copper; / therefore, when the whole molten matter, upon melting, comes to the measure of nine palas, then it is called the first amalgam, ayaḥprakāśa. / Thus is explained the all-surpassing ayaḥprakāśa amalgam.
