Ancient debris is a rare ore found in the Nether, and is the main source of netherite scraps (which can also be found in bastion chests), which can then be used to craft netherite ingots. Its high blast resistance makes it immune to normal explosions. In item form, it floats on lava and is completely immune to any form of fire.

Obtaining

[edit | edit source]

Breaking

[edit | edit source]

Ancient debris drops itself if mined by a diamond pickaxe or netherite pickaxe. If mined by any other tool, it drops nothing.

Legend
  • incorrect tool, drops nothing
  • correct tool, drops nothing or something other than the block itself
  • correct tool, drops the block itself
  • italicized can be instant mined
  1. ↑ These durations ignore any other influential factors (e.g., Mining Fatigue) and are measured in seconds. For more information, see Breaking § Speed.

Natural generation

[edit | edit source]

Ancient debris generates in the Nether in the form of scatter ores which are never naturally exposed to air.[note 1] They can only replace netherrack, basalt‌[Java Edition only], and blackstone‌[Java Edition only].

On average, Y-level 16 has the most ancient debris.

Generation of ancient debris varies by edition.

  • In Java Edition, up to two clusters may generate per chunk:
    • One cluster of 0–3 ancient debris attempts to generate with a triangle distribution from levels 8 to 24.
    • An additional cluster of 0–2 ancient debris attempts to generate evenly from levels 8 to 119.
  • In Bedrock Edition, up to five clusters may generate per chunk:
    • Two clusters of 0–3 ancient debris attempt to generate evenly from levels 8 to 23.
    • An additional three clusters of 0–2 ancient debris attempt to generate evenly from levels 8 to 119.

In Java Edition, there is an average of 1.65 ancient debris blocks per chunk[needs testing], with a normal maximum of 5.[note 2] As of Java Edition 1.16.5, on average they generate 1.56 ores per chunk. Given this number, and that there are 32768 blocks in a chunk (16×128×16), there is approximately a 0.004% chance that any randomly selected block will be an ancient debris block.

Generated loot

[edit | edit source]

Ancient debris can appear in bastion chests, either as a singular item or as a stack of two items. These two options are rolled separately from each other.

Usage

[edit | edit source]

Smelting ingredient

[edit | edit source]

Ancient debris can be smelted using a furnace or blast furnace, which gives the player netherite scrap. If a player takes out the netherite scrap, they are rewarded with 2 experience points.

Redstone component

[edit | edit source]

Because of its unique combination of being both blast resistant enough to withstand TNT and being movable with a piston, ancient debris is sometimes used as a redstone component, usually in tunnel bores.

Issues

[edit | edit source]

Issues relating to "Ancient Debris" are maintained on the bug tracker. Issues should be reported and viewed there.

Trivia

[edit | edit source]
  • The texture of the ancient debris is supposed to look like pressed metal plates.[1]
  • Ancient debris is actually what remains of the mining activity of the piglins, who extracted all the original netherite ore.[2]
  • It is possible to find blobs of up to 20 contiguous ancient debris - up to five debris can generate in a chunk, so if a blob of five generates in adjacent corners of four different chunks, a blob of 20 debris would be created.

Notes

[edit | edit source]
  1. ↑ The generation system explicitly attempts to place ancient debris where it is not exposed to air. Rarely, ancient debris can be exposed by later generation processes. It can also be exposed to fungi, or alongside smaller pockets of lava.
  2. ↑ However, it is technically possible for up to 11 ancient debris to be found in a single chunk; adjacent chunks can generate blobs on the border with up to 2 blocks spawning in an adjacent chunk.
