Furnace and Smelting
Solarpunk furnace and smelting reference for ores, metals, sand, glass, food baking, and processing routes tied to crafting progression.
The furnace is the bridge between raw gathering and higher-value crafting. Use this page when ore, glass, cooked food, or machine materials are blocking the next unlock.

Practical Route
- Build the Furnace as soon as research and materials allow it.
- Process ore before pushing deeper into machines or energy parts.
- Use Glass and processed metals to open better building and power progression.
- Keep furnace output near storage so crafting does not turn into repeated inventory trips.

How To Use This Reference
Furnace work is most valuable when a raw material is blocking a tool, machine, food, or building step. Keep ore and sand near the furnace, keep output near crafting storage, and avoid flying away with half-processed materials still sitting in the station.
