Redstone Ore

Redstone ore is the ore block from which redstone is obtained.

Deepslate redstone ore is a variant of redstone ore that can generate in deepslate and tuff blobs.

Natural generation
Redstone ore can generate in the Overworld in the form of blobs. Redstone ore attempts to generate 8 times per chunk in blobs of size 0–10, from altitudes 1 to 16, in all biomes. On average they generate 29.5 ores per chunk. Redstone ore can replace stone, granite, diorite, andesite, tuff, and deepslate. If it replaces tuff or deepslate, it will become deepslate redstone ore.

, redstone ore generates in two batches per chunk. The first batch attempts to generate 4 time per chunk, in blobs of 0–10, evenly from levels -63 to 15. The second batch attempts to generate 8 times per chunk, in blobs of 0–10, from levels -63 to -34, being more common the lower the elevation.

Breaking
Redstone ore must be mined with an iron pickaxe or higher to drop redstone dust. When mined, it drops 4–5 redstone dust (or more with Fortune, averaging at 6 redstone dust with Fortune level 3 ). If mined with Silk Touch, it drops itself instead of redstone dust.

Light
Redstone ore produces light (strength 9) and red particles when clicked, updated, or contacted by any mob (exception being a sneaking player). This effect continues until the redstone ore block receives a random block tick (averaging 68.27 seconds). This effect does not actually produce redstone power, but the block changes can be detected with an observer or a block update detector.

Subsequent clickings on a redstone ore block causes it to emit an extra burst of particles per click.

Note Blocks
Redstone ore can be placed under note blocks to produce "bass drum" sounds.
