When To Care

Care about the furnace when raw ore, sand, glass, or cooked food is blocking the next unlock. It is the key step between gathering and higher-value crafting.

Practical Use

Furnace belongs near ore, sand, food prep, and crafting storage. The value is not just processing; it is reducing the back-and-forth between raw materials and finished projects.

For machine planning, use a four-part check: input, output, energy, storage. If any part is unclear, the machine may create clutter instead of saving time.

Common Mistakes

  • Do not place Furnace away from its input, output, or power route.
  • Do not scale powered machines before adding enough generation and battery support to keep the useful devices running.
  • Do not automate a messy route. Clean storage and clear destinations first, then add drones, sprinklers, sensors, or other powered helpers.
