The generation of ores in 1.18.

An ore is any uncommon rock-type block used to obtain specific resources.

Usage[]

Ore blocks are primarily collected for crafting purposes, such as for tools and armor. Redstone dust is obtained from redstone ore or deepslate redstone ore, which can be used to create redstone circuits. Refined ore can also be combined to create a block of the material's type.

Most ores drop their resource when mined, and require a Silk Touch pickaxe to drop themselves.

Smelting ingredient[]

Ores can be smelted faster using a blast furnace.

It is not efficient to mine with Silk Touch and then smelt an ore block that normally drops multiple pieces of its resource, because smelting these ores yields less experience and only 1 piece of the resource. Nether gold ore is the only exception, as each ore block drops an average of 8.8 gold nuggets even when mined with Fortune III, which is less than a guaranteed gold ingot obtained from smelting the ore obtained using Silk Touch.

Note Blocks[]

All types of ores can be placed under note blocks to produce "bass drum" sounds.

Further uses[]

Refined ore resources can be crafted into blocks for bulk storage, for crafting recipes or for decoration. Coal blocks and most mineral blocks are crafted by putting 9 of the refined material items in a square. Nether quartz is the only Mineral block that only needs 4 items to be crafted.

Any processed ore

Any raw ore

All of the above block recipes are reversible, excluding quartz and oxidized copper.

Iron and Gold ingots can be converted into nuggets and vice-versa.

Lapis Lazuli can be crafted into a dye, or even used as one.

Lapis Lazuli

Netherite scraps, obtained by smelting ancient debris, are used alongside gold ingots to create netherite ingots. This is the only mineral used alongside another mineral to create an alloy.

Ingredients Crafting recipe
Gold Ingot, Netherite Scrap

Netherite ingots can be used on a smithing table to upgrade diamond items to netherite items. Data such as durability, enchantments, and custom names are preserved.

The following is the distribution of ores according to the altitude (layers are number of blocks above the lowest layer of bedrock) in the Overworld and the Nether. The highest layers that gold, redstone, diamond, and lapis lazuli ore can be found on are two layers lower.[1]

Overworld[]

For the pre-1.17 ore distribution, see Ore/Pre-1.17 distribution.

  1. This refers to coal ore blocks spawned in blobs and not as parts of fossils or mansion forges.
  2. Instead of multi-block blobs, emerald ore is placed in scattered blocks.
  3. Deepslate variants only generate in deepslate blobs between layers 0 and 16.
  4. Unlike most other ores, lapis lazuli's frequency peaks around layer 15, and slowly tapers off above and below.
  5. Deepslate variants replace only Deepslate and Tuff.
  6. This refers to coal ore blocks spawned in blobs and not as parts of fossils or mansion forges.
  7. Instead of multi-block blobs, emerald ore is placed in scattered blocks.
  8. Deepslate variants only generate in deepslate under layer 0. Deepslate Emerald Ore doesn't generate naturally.
  9. The block which allows to distinguish its large ore veins.
  10. It features very large blobs, most times as double as big than a normal blob.
  11. They can only generate under very specific circumstances. Because they can only generate above Y=0, an ore has to generate at Y=1 and then stretch below Y=0. There also has to be deepslate to replace which is uncommon above Y=-3.
  12. Deepslate variants replace only Deepslate and Tuff.
  13. While Coal, Copper and Emerald technically can replace Deepslate and Tuff, as they do not generate on layers under 0, they can't replace them naturally.
  14. Unlike most other ores, ancient debris' frequency peaks at layer 15, and quickly tapers off above and below.

Trivia[]

  • Ancient debris has two ways to generate, similar to gold ore.
  • Since it is exclusive to only one Overworld biome, emerald ore is actually rarer than ancient debris per chunk.
