Bronze in "War Dynasty" is a very important special material in the game. If you want to use a smelting furnace to make bronze, you can first buy copper ore, tin ore and 3 units of firewood. Each smelting furnace can be queued at the same time. 20 bronze ingots, but can only be smelted one at a time.
How to make bronze in the smelting furnace of the Warring Dynasty
Once the smelting furnace is built, you will need three raw materials to use it to smelt bronze:
Copper Mine
Tin Mine
3 units of firewood
Each smelting furnace can queue up to 20 bronze ingots at the same time, but only one can be smelted at a time. Each bronze ingot takes a few minutes to produce, so it's best to put all the ingredients into the smelting furnace and then go do other things. When you return, you can collect all the bronze ingots produced.
It is important to note that charcoal cannot be used in place of firewood to produce bronze.
