Tuff can generate in the Overworld in the form of blobs. Tuff attempts to generate 2 times per chunk in blobs of size 0-160, from elevations 0 to 16, in all biomes. In Java Edition 1.18[upcoming], tuff attempts to generate 2 times per chunk in blobs of size 0-862, from elevations -63 to 16, in all biomes.
Any ore that generates in tuff becomes its deepslate variety. Tuff also generates occasionally in the deepslate layer below Y=0.
Tuff drops as an item if mined by any pickaxe. If mined without a pickaxe, it drops nothing.
- Times are for unenchanted tools as wielded by players with no status effects, measured in seconds. For more information, see Breaking § Speed.
Tuff is currently used only for decoration. It cannot be crafted into anything else.

- In real life, tuff is a strong type of igneous rock which forms from compressed ash resulting from volcanic eruptions, which sees extensive use in Armenian architecture. Tuff in Minecraft is somewhat similar, with the texture representing that of a rough, uneven surface which appears to be the result of volcanic ash formation.
