Which consequence arose when early Chinese gunpowder recipes used sulfur?

💡 Explanation

A lower ignition temperature was advantageous because sulfur acts as a flux, aiding the reaction, rather than hindering deflagration temperatures; therefore, ignition temperature decreased earlier, rather than the burn rate slowing.
