Cupola Furnace Core
Starts the Cupola furnace.
Place the core first, then ctrl plus shift plus right-click it to raise the build outline of the Cupola furnace and its shopping list; the walls, the tuyere, the taps and the hopper go on around it. Its side variant fixes which way the furnace faces and the layout turns with it, and it wears the refractory tier it was crafted from. It carries the same readout as the blast furnace's core, because it is the same machine on different data: the state, the heat balance, and the reasons a lit shaft stalls.
