Production processes
Conversions, fuel byproducts and device recipes. Each batch uses the input quantities shown below.
Fuel byproductWood → Charcoal
An average over many operations, not a guaranteed result for this quantity. Fractional output uses probabilistic rounding. Chance per consumed fuel unit: 75%.
Native fuel reserve per item: 10. This is not a duration: oven drain scales with temperature. Charcoal requires a device that permits byproducts.

Native progress per consumed item: 30 sec. This is progress, not elapsed device time. The device divides its speed among active input stacks; pause, power, fuel and free output space affect completion.
Device time scenario
- Selected stack completion
- 0.17 min
Scenario for the selected quantity in one input stack, with a constant active-stack count and native device speed. Assumes continuous fuel/power, valid temperature and free output slots. Pauses and server overrides are excluded.
