The Casting Basin is a T4 smelter machine that together with the Blast Furnace can rapidly process ore. Up to 4 Blast Furnaces can be connected to a single Casting Basin. This turns liquid metal into bars at a high rate. Capable of dealing with Chromium and Molybdenum. Build in a 5x3x5 configuration (75 total). The Casting Basin does not require power. If built outside the Cold Cavern, it will display "Warning! Basin Overheating! Place somewhere much colder!"
