During the Han Dynasty, which vulnerability arose when improving efficiency in cast iron salt production?

💡 Explanation

Faster annealing of cast iron resulted in components with higher sulfur content introducing sulfur embrittlement, because the rapid cycle did not allow sufficient diffusion from the metal; therefore structural integrity was weaker, rather than more robust as intended without sulfur reducing the iron’s melting point.
