Ancient Debris

Ancient debris is a rare ore found in the Nether, and is the only source of netherite scrap. It floats on lava in item form and it cannot be burned. It also has an extremely high blast resistance, meaning it cannot be blown up.

Mineral veins
Ancient debris generate in the Nether in the form of mineral veins. Two veins generate per chunk: one vein of 1–3 ancient debris generates with a periodic Gaussian distribution (similarly to lapis lazuli ore) between levels 8–22, and an additional vein of 1–2 ancient debris generates randomly between levels 7–119. There are up to 5 ancient debris blocks per chunk. Ancient debris will never generate exposed to air, meaning it will always be covered by netherrack or lava.

Obtaining
Ancient debris drops as an item if mined by a diamond pickaxe or better. If mined by any other tool, it drops nothing.
