FAQs

Why does the text list many organic substances (urine, dung, bile, plant materials)?

As practical workshop inputs: they function as fluxes, reducing/cleaning agents, binders, or coatings that help separate slag/impurities so the metal ‘flows out’ cleanly.

What is the administrative logic behind specifying additives?

It standardizes state workshop recipes to ensure predictable output and to audit whether foremen follow prescribed methods (reducing waste and pilferage).
