Composting
A Composter needs 7 layers of compost to produce 1 Bone Meal, and each item put in has a 30% to 100% chance of adding a layer.
Rules
| Layers needed | 7 layers of compost fill a Composter. The filled Composter then produces 1 Bone Meal. |
| First item | The first item put into an empty Composter always adds a layer. |
| Later items | With 1 to 6 layers, each item adds 1 layer with its own chance: 30%, 50%, 65%, 85% or 100%. The item is used up whether or not a layer is added. |
| Becoming ready | 1 second (20 game ticks) after the 7th layer, the compost turns into Bone Meal that can be collected. |
| Collecting | Using the ready Composter drops 1 Bone Meal and empties it. |
| Full Composter | A Composter with 7 layers, or with Bone Meal ready, takes no more items. |
| Hoppers | A Hopper above feeds compostable items in while there are fewer than 7 layers. A Hopper below takes the Bone Meal out. Hoppers at the sides neither insert nor remove anything. |
| Comparator | Signal strength equals the number of layers: 0 when empty, 7 when full, 8 when Bone Meal is ready. |
