Smeltery Recipes Documentation

This document explains how to define and add recipes for the Smeltery system using JSON configuration files.

JSON Structure​

{
  "type": "industrialupgrade:smeltery",
  "operation": "<operation_type>",
  "inputs": [
    {
      "type": "<item|fluid|tag>",
      "id": "<namespace:id>",
      "amount": <integer>
    }
  ],
  "outputs": [
    {
      "type": "<item|fluid|tag>",
      "id": "<namespace:id>",
      "amount": <integer>
    }
  ]
}

Fields​

  • operation – Defines the recipe type.

    • furnace
    • castings_ingot
    • castings_gear
    • mix

  • inputs – A list of recipe inputs. Each input can be:

    • item – Requires an item ID from the item registry.
    • fluid – Requires a fluid ID from the fluid registry.
    • tag – Requires an ore dictionary tag.

  • outputs – A list of recipe outputs. Same format as inputs.

  • amount – Stack size for items, or millibuckets (mB) for fluids.

Recipe Types​

1. Furnace Recipe (furnace)​

Converts an item input into a fluid output.

Example: Smelting Iron Ore into Molten Iron.

{
  "type": "industrialupgrade:smeltery",
  "operation": "furnace",
  "inputs": [
    {
      "type": "item",
      "id": "minecraft:iron_ore",
      "amount": 1
    }
  ],
  "outputs": [
    {
      "type": "fluid",
      "id": "iu:molten_iron",
      "amount": 144
    }
  ]
}

2. Ingot Casting (castings_ingot)​

Casts a fluid input into an item output (ingot).

Example: Casting Molten Iron into Iron Ingot.

{
  "type": "industrialupgrade:smeltery",
  "operation": "castings_ingot",
  "inputs": [
    {
      "type": "fluid",
      "id": "iu:molten_iron",
      "amount": 144
    }
  ],
  "outputs": [
    {
      "type": "item",
      "id": "minecraft:iron_ingot",
      "amount": 1
    }
  ]
}

3. Gear Casting (castings_gear)​

Casts a fluid input into an item output (gear).

Example: Casting Molten Iron into Iron Gear.

{
  "type": "industrialupgrade:smeltery",
  "operation": "castings_gear",
  "inputs": [
    {
      "type": "fluid",
      "id": "iu:molten_iron",
      "amount": 576
    }
  ],
  "outputs": [
    {
      "type": "item",
      "id": "iu:iron_gear",
      "amount": 1
    }
  ]
}

4. Fluid Mixing (mix)​

Mixes two or more fluid inputs into a new fluid output.

Example: Mixing Molten Copper and Molten Tin into Molten Bronze.

{
  "type": "industrialupgrade:smeltery",
  "operation": "mix",
  "inputs": [
    {
      "type": "fluid",
      "id": "iu:molten_copper",
      "amount": 144
    },
    {
      "type": "fluid",
      "id": "iu:molten_tin",
      "amount": 48
    }
  ],
  "outputs": [
    {
      "type": "fluid",
      "id": "iu:molten_bronze",
      "amount": 192
    }
  ]
}

Notes​

  • 144 mB = 1 ingot (standard unit).
  • Tags can be used as inputs to generalize recipes.
  • Only valid combinations of operation + inputs/outputs will be registered.
