Its lethality is extremely limited, and in many cases it can only intimidate the enemy.

Zhao Ning said: "Is it based on the ratio I gave you last time?"

"Yes." Chen Gui handed over the documents from the manufacturing process.

The main ingredients for making gunpowder are nitrate, sulfur, and carbon.

But it's not just these three materials that can make a bomb.

The core is the ratio of materials.

However, ancient weights and measures and refining containers cannot quickly and accurately measure the proportions of the three substances.

This is the biggest problem facing Zhao Ning.

For example, the nitrate in gunpowder is mainly potassium nitrate. How to extract high-concentration potassium nitrate?

The gunpowder ratio recorded in the Song Dynasty's "Wu Jing Zong Yao" is nitrate 48.66%, sulfur ratio 17.03, carbon is not recorded, and some are other impurities.

The 19th-century French chemist Bertrault's gunpowder ratio was 82.28% nitrate, 9.78% sulfur, and 7.94 carbon.
