Furnace fuel
Fuel burns out twice as fast in a Smoker or Blast Furnace as in a Furnace, and each item cooks in half the time.
Rules
| Cooking time | 10 seconds (200 game ticks) per item in a Furnace. 5 seconds (100 game ticks) per item in a Smoker or Blast Furnace. |
| Burn time | In a Smoker or Blast Furnace every fuel lasts half as long as in a Furnace, rounded down to whole game ticks. |
| Coal and Charcoal | 80 seconds in a Furnace, 40 seconds in a Smoker or Blast Furnace. Both cook 8 items. |
| Other fuels | In a Furnace: Lava Bucket 1,000 seconds (100 items), Block of Coal 800 seconds (80 items), Blaze Rod 120 seconds (12 items), planks and logs 15 seconds (1.5 items). |
| When fuel is used | A new piece of fuel is used only when there is an item to cook and room for its result. |
| Fire goes out | If the fire goes out with an item partly cooked, its progress drops by 2 game ticks per tick, twice as fast as it built up. |
