  },

}

Examples

Iron Ingot → Molten Iron

{
  "type": "hephaestus:melting",
  "ingredient": { "item": "minecraft:iron_ingot" },
  "result": { "id": "hephaestus:molten_iron", "amount": 90 },
  "fuel": { "id": "minecraft:lava", "amount": 100 },
  "temperature": 600,
  "time": 200
}

Blaze Rod → Molten Blaze (high temperature)

{
  "type": "hephaestus:melting",
  "ingredient": { "item": "minecraft:blaze_rod" },
  "result": { "id": "hephaestus:molten_blaze", "amount": 250 },
  "fuel": { "id": "hephaestus:molten_blaze", "amount": 50 },
  "temperature": 800,
  "time": 300
}

Notes

  • time is measured in ticks (20 ticks = 1 second)
  • fuel.amount is consumed once when the recipe completes, not per tick
  • The melter requires the fuel tank block directly below it
  • Both the Melter and Smeltery use this recipe type
