Is the Smelter the only automated way to turn a solid metal item to a liquid in a pipe or tank?
You can pipe fluids into a mold just fine. But what about the other way around? Do you have to manually use ceramic jugs + funnels to put liquid metal in a pipe?
One jug can hold 13 ingots and 8 nuggets of molten iron that won't cool down, which is handy, but manual.
Fluid -> item is easy.
Item -> fluid can only be done with a Smelter?
