When three parts of tapaníya (pure gold) are melted with thirty-two parts of sveta-tára, the compound becomes reddish white (svetalohitakam). When three parts of tapaníya are combined with thirty-two parts of copper, the compound becomes yellow (píta, red!). Also when three parts of the colouring ingredient (rágatribhága, i.e., tíkshna referred to above) are heated with tapaníya, the compound becomes yellowish red (píta). When two parts of sveta-tára and one part of tapaníya are heated, the whole mass becomes as green as mudga (Phraseolus Mungo).
