Furnace
Production Building • Tier 1
Overview
The Furnace is the cornerstone of metal production in StarRupture, transforming raw ores into refined ingots that are essential for advanced crafting. This heat-based processing station can operate using either fuel (coal, wood, biofuel) or electrical power, making it flexible for both early and late-game setups. Smelting is a fundamental process that unlocks the entire technology tree, as nearly every advanced item requires metal ingots. The furnace's simple design and low entry cost make it one of the first production buildings you'll construct.

Building Cost
- Stone x20 - Mine from rock deposits
- Iron Ore x10 - Mine from iron deposits (requires pickaxe)
- No power required initially - Can use fuel
- Build time: 10 seconds
- Requires "Smelting" technology (100 DP)
- Needs flat, stable ground for placement
Usage Details
- Ore Smelting: Convert Iron Ore, Copper Ore, and other ores into ingots
- Fuel Options: Burns coal (most efficient), wood, or biofuel
- Power Mode: Connect to electrical grid for automated operation
- Processing Time: 5 seconds per ore (varies by type)
- Batch Processing: Queue multiple items for continuous smelting
- Output Storage: Holds up to 10 stacks of processed materials
Strategy Tips
- Build 2-3 furnaces early game to keep up with metal demand
- Place near mining operations to reduce ore transport time
- Stockpile coal before major smelting sessions
- Connect to power grid mid-game for hands-free operation
- Use conveyor belts to automate ore input and ingot output
- Keep one furnace dedicated to iron, another for copper
- Upgrade to electric power when you have stable energy supply
