Bloomery
A chimney-shaped furnace for smelting ores.
Notes
The Bloomery is a mid-game furnace that smelters use to convert copper, gold, and iron ores into ingots, and it also produces cast-iron furniture and the Smelting Basic Upgrade module. It must be placed inside an enclosed room of at least Tier 2 (typically brick construction) with 28 m³ of free space, and it requires a steady supply of burnable fuel at 10 J/s to operate. For efficient smelting, install a Smelting Basic Upgrade module to reduce resource and labor costs, and remember that ore processing generates tailings that must be stored or disposed of to avoid ground pollution.
