Iron sand washed out of river sand; the tatara furnace turns it into tamahagane with charcoal.
Obtaining
Washing Sluice2→10s2+2
Usage
Washed out in the sluice
Load the sand you dug at the river into the sluice and put a water bucket in the slot underneath. The sand moves into the washing slots a scoop at a time, and once they are full the wash begins: the heavy grains settle out and the spoil that washed off comes back as ordinary sand in the byproduct slot.
