Stone brick — Factorio Production Calculator
Stone brick is crafted in the furnace in 3.2 seconds, producing 1 per craft from 2 × Stone. At 60 per minute you need 3.2 furnaces, and the chain behind it draws on 1 raw resources: stone.
Production chain for 60 Stone brick / minute
| Item | Per minute | Machines | Machine |
|---|---|---|---|
| Stone brick | 60 | 3.2 | Furnace |
Raw materials
| Resource | Per minute |
|---|---|
| Stone | 120 |
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 brick recipe
| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Furnace | 3.2 s | 1 | Stone × 2 |
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 3 machines and nothing else to build.
Belt check: the busiest input here moves 120 per minute, which is 0.13 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 brick
5 base-game recipes consume stone brick, sorted by how much each one takes:

- Steel furnace — 10 per craft
- Concrete — 5 per craft
- Wall — 5 per craft
FAQ
How many furnaces do I need for 60 stone bricks per minute?
3.2 furnaces. One at standard speed produces 18.8 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 brick take?
At 60/min the chain consumes 120 stone per minute. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
Is stone brick needed for science packs?
Not directly. It feeds Electric furnace and Oil refinery, and those in turn feed the science packs. Open the science pack page to see the demand that lands on this recipe.
