तपनीयं ज्येष्ठं सुवर्णं सुरागं सम सीस अतिक्रान्तं पाक पत्त्र पक्वं सैन्धविकया उज्ज्वालितं नील पीत श्वेत हरित शुक पत्त्र वर्णानां प्रकृतिर् भवति ॥

sanskrit

Pure and glittering gold is tapaníya. This combined with an equal quantity of lead and heated with rock-salt (saindhav'ika) to melting point under dry cowdung becomes the basis of gold alloys of blue, red, white, yellow (harita), parrot and pidgeon colours.
