I am having trouble with metalworking. Currently i am attempting to make black bronze, however, i am finding it quite difficult to heat unshaped copper high enough to make it liquid. I have put it in a forge that is unobstructed and has a bellows. however, i am unable to heat past orange**. the heat bar is up on the yellow-whitish area though. Edit: It seems it is necessary to have extra coal in each slot in the forge to heat up each slot. I assumed that was just to keep extra fuel in the forge so it needed less intervention Also, what are good ways to keep metals heated? I noticed storing ingots and unshaped metals in anvils keeps them warm. Is this intentional? I really like this feature. I currently am working on making at least 1 type of every anvil surrounding my forge to store heated metals to be worked into 2x ingots and alloys. Also, how do you make ingot piles? I read that you could, but i cannot figure out how to. The wiki doesn't say how either. Edit: I was foolishly trying to stack heated ingots. Finally, when using bellows on a forge, is it necessary to place it inside the 3x3 area? Or can you have it bordering? I cant seem to get it to work unless it is inside the area, but im afraid it is keeping it from reaching it's highest temp. The heat bar never is able to go up to the maximum height of the meter.
