This is my semi-automatic smelter / foundry. It drops coal from the kilns up top through a funnel into the center of the building, from there you can either store it or run around the back side of the smelters and fill them up. The blacksmith shop has all the items to make a level 7 forge and level 5 workbench. The blacksmith hut has a blast furnaced in it to smelt black metal.
