Crucible Hearth
Four melting holes over a grate, each a clay stand for one crucible, with the coke packed around them. Charge it with fuel as you would any firebox; the ash falls through into the pit below.
Right-click a hole with a charged pot to seat it, and which cell is clicked decides which hole takes it. See Crucible furnace.
