Furnace

To build: 6 Clay, 6 Stone, 4 Large Stone.

Build time about 5s (quicker with a better hammer).

Can be placed on almost any open ground.

Raised with a building hammer in your pack, and repaired by striking it with one in hand.

Requires a Wood Hammer or better to build or repair.

Smelt Iron Ore into Iron and refine Sulphur Rock — aim at it and press E to open. It burns wood as a camp fire does: keep the fuel slot loaded, or the fire dies and the smelting stops where it stands.

Needs the Metallurgist skill to work.
