as the title says the only one way you can get from is from trading. every time i want to craft bronze ingot from modern industrialization it's always go back to tech reborn. i need it for continuing the quest because tech reborn bronze can't register the quest

You want to make bronze dust. With copper and tin dust in the crafting grid. Then smelt that into the ingot...

already tried and it's always gets converted to tech reborn. do i need to smelt it in modern industrialization furnace or smth?

why do you need specifically MI bronze?
