I'm trying to make smooth stone by smelting stone in a furnace since that's how you make smooth stone but it refuses to smelt. I'm trying to make some blast furnaces which you need smooth stone for but since the game is not letting me make smooth stone, I can not make them. I even tried putting stone in the stonecutter even though I know it doesn't work but I wanted to see and it's not an option either. I have not seen anyone else report this yet and I would love this to be fixed.
