Tuff is an ornamental rock formed from volcanic ash, occurring in underground ore blobs below Y=16.
Obtaining
Natural generation
Tuff can generate in the Overworld in the form of ore blobs. Tuff attempts to generate 2 times per chunk in blobs of size 0-864, from elevations -64 to 0, in all biomes. Tuff can replace stone, andesite, diorite, granite, polished andesite[BE only], polished diorite[BE only], polished granite[BE only], and deepslate. Any ore that generates in tuff becomes its deepslate variety.
Additionally, tuff can generate in an ore vein that consists of iron ore below Y=0.
Breaking
Tuff drops as an item if mined by any pickaxe. If mined without a pickaxe, it drops nothing.

History
| October 3, 2020 |  Tuff is shown unnamed at Minecraft Live 2020 as part of an amethyst geode. | ||||
|---|---|---|---|---|---|
| Java Edition | |||||
| 1.17 | 20w45a | Added tuff.
| |||
| Tuff generates as part of amethyst geodes. | |||||
| November 18, 2020 |  JAPPA tweets an image of an alternate tuff texture. | ||||
| 1.17 | 21w08a | Tuff no longer generates as part of amethyst geodes and instead generates in patches below Y=0. | |||
| 21w11a | Ores that spawn in tuff now convert to their deepslate variant. | ||||
| 21w15a | Tuff blobs now also generate between Y=0 and Y=16. | ||||
| Due to Caves and Cliffs being split into two parts, tuff now generates only between Y=0 and Y=16. because the world generation has been reverted and moved to the Caves & Cliffs Prototype Data Pack. | |||||
| 21w16a | If the prototype data pack is applied to a world, tuff can now generate as part of iron ore veins below Y=0. | ||||
| 1.18 | Experimental Snapshot 1 | All previous changes to tuff generation from the prototype data pack have now been implemented into the base game. | |||
| Bedrock Edition | |||||
| 1.17.0 | beta 1.17.0.50 | Added tuff. | |||
| beta 1.17.0.52 | Tuff is no longer only available through Experimental Gameplay. | ||||
| 1.18.0 | beta 1.18.0.20 | Tuff blobs are now able to generate below Y=0.[1] | |||

Trivia
- 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.
