Which outcome occurred more acutely when the proportion of sulfur increased above optimal amounts Chinese cast iron-barrel hand cannons using early gunpowder?

💡 Explanation

Barrel fracturing increased via sulfur induced embrittlement; because excess sulfur reacted with free iron at bore surface forming iron sulfides, therefore, making the structure brittle rather than improving propulsion as intended.
