Tuff

BE

Tuff is a rock formed of volcanic ash, occurring in mineral veins below Y=16.

Breaking
Tuff drops as an item if mined by any pickaxe. If mined without a pickaxe, it drops nothing.

Natural generation
Tuff can generate in the Overworld in the form of mineral veins. Tuff attempts to generate 2 times per chunk in veins of size 0-862, from elevations -63 to 16, in all biomes. Tuff can replace stone, diorite, andesite, granite, and deepslate.

Any diamond ore, gold ore, iron ore, lapis lazuli ore, or redstone ore that generates in tuff will become its deepslate variant.

Usage
Tuff is currently used only for decoration.
