The 'cooking' station for everything beyond the Fabricator. Smelts Ingots (Titanium/Copper/Silver/Gold/Germanium/Plasteel/Mangalloy) and processes biochemistry (Necrolei Cysts → Strong Acid, Fibrous Pulp → Biofuel Block / Water, Celestine → Strontium).

Required for every Ingot recipe, Strong Acid, Biofuel Block, Strontium, and the Water-from-Pulp chain. Build alongside your Fabricator on day one — they are the two-station foundation of every base.
