Stone furnace — Factorio Production Calculator
Stone furnace is crafted in the assembling machine in 0.5 seconds, producing 1 per craft from 5 × Stone. At 60 per minute you need 1 assembling machine, and the chain behind it draws on 1 raw resources: stone.
Production chain for 60 Stone furnace / minute
| Item | Per minute | Machines | Machine |
|---|---|---|---|
| Stone furnace | 60 | 1 | Assembling machine |
Raw materials
| Resource | Per minute |
|---|---|
| Stone | 300 |
Machine counts are not rounded up. Add a little headroom in game — belt throughput and inserter speed usually mean you want 5-10% more than the exact number.
Stone furnace recipe
| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Assembling machine | 0.5 s | 1 | Stone × 5 |
What the whole chain needs
This recipe has no intermediate steps: every ingredient is a raw resource, so the chain is a single machine block fed straight from mining or pumpjacks. At 60 per minute that is 1 machine and nothing else to build.
Belt check: the busiest input here moves 300 per minute, which is 0.33 of a yellow belt's 900 per minute. Above 1.0 and you need a second belt (or a faster tier) before the machines themselves become the limit.
What uses stone furnace
2 base-game recipes consume stone furnace, sorted by how much each one takes:
- Boiler — 1 per craft
- Burner mining drill — 1 per craft
FAQ
How many assembling machines do I need for 60 stone furnaces per minute?
1 assembling machine. One at standard speed produces 60 per minute, so 60 ÷ that number is the count. The calculator above rounds nothing — add 5-10% headroom for belt and inserter losses in a real factory.
How much raw ore does stone furnace take?
At 60/min the chain consumes 300 stone per minute. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
Is stone furnace needed for science packs?
Not directly. It feeds Boiler and Burner mining drill, and those in turn feed the science packs. Open the science pack page to see the demand that lands on this recipe.
