Which consequence resulted from decreased sulfur purity during Ming Dynasty gunpowder production?

💡 Explanation

Lower sulfur purity slowed black powder's deflagration because it reduced exothermic sulfide formation, causing lower flame temperature. Therefore propellant burned less vigorously reducing muzzle energy, rather than increasing projectile velocity or degrading iron faster.
