awesome!

Where is my kiln? Must try at home!

I guess they preheat the sword mold to keep it from exploding when you pour stuff in it?

im curious about the forging of it tho, thought you would hammer the metal out and shit to make it harder. Wonder if during the Bronze Age swords were made out of just one piece like this without forging

Metal shop was never this dramatic. We needed the music and hushed voices like the masters.

Partly. The mold would definitely break if heated too quickly (either in the furnace or with the bronze being poured in) but it is also heated so the bronze doesn't cool and harden before all of it is poured in.

Bronze swords, unlike iron/steel, are cast in a mold, then (since about 2000 BC) the edges are forged with hammer and anvil to give it hardness and strength. >> ^deathcow:
