Silver (tāra), or partially purified silver, should be processed: four (times/parts) with bone-tuttha, four with equal lead, four with dry tuttha; (then fired) in a crucible/pot (kapāla) three times, in cow-dung fuel twice—thus, after surpassing seventeen tuttha-treatments, it is fired with a saindhavika additive.
Counted steps make the process inspectable and enforceable—officials can verify compliance and assign liability for deviations.
