Alloy Recipe

⚗️ Alloy Recipe

Type: hephaestus:alloy
Machine: Smeltery only

Combines two or more fluids inside the smeltery tank into a single output fluid. Alloying happens automatically when all input fluids are present in the correct amounts.

How it Works

Every tick, the smeltery checks:
  1. Are ALL input fluids present in sufficient amounts?
  2. Is the temperature high enough?
  3. Is there space in the tank for the output?

If yes → consume inputs, produce output

Alloying is continuous — it will keep producing as long as all inputs are available.

Examples

Bronze (Copper + Tin)

{
  "type": "hephaestus:alloy",
  "inputs": [
    { "id": "hephaestus:molten_copper", "amount": 288 },
    { "id": "hephaestus:molten_tin",    "amount": 144 }
  ],
  "output": { "id": "hephaestus:molten_bronze", "amount": 432 },
  "temperature": 600
}

Brass (Copper + Zinc)

{
  "type": "hephaestus:alloy",
  "inputs": [
    { "id": "hephaestus:molten_copper", "amount": 288 },
    { "id": "hephaestus:molten_zinc",   "amount": 144 }
  ],
  "output": { "id": "hephaestus:molten_brass", "amount": 432 },
  "temperature": 600
}

Electrum (Gold + Silver)

{
  "type": "hephaestus:alloy",
  "inputs": [
    { "id": "hephaestus:molten_gold",   "amount": 144 },
    { "id": "hephaestus:molten_silver", "amount": 144 }
  ],
  "output": { "id": "hephaestus:molten_electrum", "amount": 288 },
  "temperature": 700
}

Three-way alloy

{
  "type": "hephaestus:alloy",
  "inputs": [
    { "id": "hephaestus:molten_copper",  "amount": 144 },
    { "id": "hephaestus:molten_silver",  "amount": 144 },
    { "id": "hephaestus:molten_gold",    "amount": 144 }
  ],
  "output": { "id": "yourmod:molten_trinium", "amount": 432 },
  "temperature": 900
}

Notes

• There is no limit to the number of inputs (minimum 2)
• Input fluids are consumed in the exact amounts specified — no partial crafting
• Output is added to the tank. If the tank is full, alloying pauses
• Multiple alloy recipes can be active simultaneously if different fluids are present
