Bronze is the second tier next to stone. It is the first metal available to players. Bronze is created by crafting one Tin Ore and one Copper Ore near a furnace. This is how a Bronze Bar is created. A tin bar or a copper bar cannot be created and they have to be smelted together to create bronze.
NOTE: Yes, I know it's kinda useless and all but, I really wanted to contribute to this or something. It was a mistake until I realized it's a real page with "WIP" in it. So I did this.
