← HistoryDuring 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.
