{gold:: refreshing its colour (?)}
karṣapramāṇaṃ tu suvarṇapatraṃ śarāvaruddhaṃ paṭudhātuyuktam /
aṅgārasaṃsthaṃ praharārdhamānaṃ dhmātena tatsyānnanu pūrṇavarṇam //

A gold leaf of the measure of one karṣa, enclosed in earthen shallow dishes with rock salt, / placed on burning coals and blown with bellows for the measure of half a prahara, will indeed attain full colour.
