षट्त्रिंशदङ्गुलमञ्जनवर्णं सामूरम् ॥ कZ_०२.११.८९ ॥
ṣaṭtriṃśadaṅgulamañjanavarṇaṃ sāmūram
Le sāmūra est (spécifié comme) long de trente-six aṅgulas (en mesure) et de la couleur du khôl/antimoine (noir sombre).
It standardizes acceptance and pricing, prevents under-delivery, and simplifies auditing of storehouse issues and workshop consumption.
Color is a quick inspection proxy for processing method, dyeing, and grade; it helps detect substitution or defective curing.
