This Is My Primitive Tribe

After making the first bronze hammer, Jiang Xuan first smelted a large pile of copper ore and tin ore twice, casting them into copper and tin blocks using clay molds.

Then, he first cast a Bronze Short Knife about thirty centimeters long and ground the blade very thin on a stone.

However, when he tested the Bronze Short Knife, a serious problem arose: the edge was too soft, and after two chops on a tree, the edge was directly rolled.

"How could this be?"

Jiang Xuan, holding the Bronze Short Knife, scratched his head, feeling that something must have gone wrong somewhere.

The bronze hammer he made before worked perfectly, so why did the same Bronze Liquid fail when forming a Bronze Knife?

Jiang Xuan knew clearly that bronze could indeed be made into weapons because he had seen a replica Bronze Knife in his previous life, which was quite sharp.

"Could it be that bronze also needs to be quenched like iron?"

Jiang Xuan frowned and thought for a long time, deciding to give it a try.

He first placed the Bronze Short Knife in the furnace, heated it until it was red-hot, and then used a wooden stick to clamp the knife and immerse half of the blade in cold water.

"Hiss hiss hiss..."

The water surface that came into contact with the Bronze Short Knife instantly boiled, releasing a large amount of steam.
