Ancient debris is a rare ore found in the Nether, and is the main source of netherite scrap. It floats on lava in item form and it cannot be burned by any other forms of fire. It also has an extremely high blast resistance, meaning it cannot be blown up under normal circumstances.



Ancient debris spawn rate per layer; Y=15 has the most ancient debris. Average only.

Ancient debris generates in the Nether in the form of mineral veins. Up to two veins may generate per chunk: one vein of 1–3 ancient debris attempts to generate with a periodic normal distribution (similarly to lapis lazuli ore) from levels 8 to 22, and an additional vein of 1–2 ancient debris attempts to generate randomly from levels 8 to 119. There is an average of 1.7 ancient debris blocks per chunk, with a normal maximum of 5. However, it is technically possible for up to 13 ancient debris to be found a single chunk; adjacent chunks can generate veins on the border with up to 2 blocks spawning in an adjacent chunk. Ancient debris never generates naturally exposed to air and can only replace netherrack, basalt, and blackstone.[1] On average, y-level 15 has the most ancient debris.


Ancient debris drops as an item if mined by a diamond or netherite pickaxe. If mined by any other tool, it doesn't drop anything.

  • The texture of the ancient debris is supposed to look like pressed metal plates.[2]
  • Ancient debris yields the most experience of any item when smelted.
  • Ancient debris is actually what remains of the mining activity of the piglins, who extracted all the original netherite ore.[3]
