History

During early Chinese gunpowder development, which risk increased in blast furnace operations to adjust compositions?

A)Formation of more brittle cast iron
B)Premature ignition of explosive mixtures
C)Increased rates of crucible cracking
D)Formation of non-reactive slag inclusions

💡 Explanation

Premature ignition risks augmented because mixing processes optimized for black powder created sparks, therefore increasing deflagration events rather than controlled explosions because sensitive mixtures ignited outside enclosed spaces.
