Minecraft Composter and Furnace Fuel Calculators
Bone meal from any compostable item and fuel for any smelting job, worked out from the chances and burn times Java 26.3 keeps in its own item data.
Loading the Java 26.3 item data…
Seven layers make one bone meal. The first item into an empty composter always adds a layer; every later item rolls its chance, and a failed roll still uses the item up.
| Item | Chance | Per bone meal | Average for your target | 95% sure |
