Obsidian is a dark block known for its high blast resistance and strength.

Obsidian is the sole block that can be successfully mined only with a diamond pickaxe.

Enchanting a pickaxe with "Efficiency" and using a beacon with Haste both drastically decrease the mining time. See the obsidian farming tutorial for more information.

Lava and water

Using a water spring to mine obsidian.

Obsidian is formed when flowing water hits a lava source block, and can be found naturally where water from a spring or lake has flowed over a nearby lava pool.

Natural generation

Obsidian can be created when a Nether portal is generated in the Nether or the Overworld. This portal can then be mined, providing a way of obtaining obsidian renewably.

When a player enters the End, a platform of 25 obsidian blocks is generated for the player to spawn on. This platform can then be mined, and will be regenerated when the player reenters the End. Solid pillars of obsidian can also be found on the surface, which will regenerate when the ender dragon is respawned. Obsidian also generates as a part of end ship in end cities.

Obsidian also occurs naturally where underwater springs flow onto lava, often at layer 10 or lower.

Obsidian also generates in woodland mansions in a tree shape with a diamond block in the middle of it.


Obsidian can be found in 25.6% of village blacksmith chests in stacks of 3–7, and in 8.0% of nether fortress chests in stacks of 2–4.

Ender chests

When an ender chest is mined with a pickaxe without the Silk Touch enchantment, it drops 8 obsidian.


Obsidian can be used to build explosion resistant structures. At 6,000, obsidian's explosion resistance is the highest you can obtain in Survival mode, other than anvils which have the same blast resistance. Obsidian cannot be pushed by pistons. Obsidian is also notoriously known in servers as a defense block. It is common in many builds as building armor and is essential for protection.

Nether portals

Obsidian can be used to create a nether portal frame, which can then be ignited using fire. The frame will be a vertical rectangle any size from 4×5 to 23×23. Note that the corners of the frame are not required.

Issues relating to "Obsidian" are maintained on the bug tracker. Report issues there.


  • Obsidian is one of the hardest blocks to destroy in Minecraft. In reality, obsidian is glass-like in texture and quite fragile.
  • In real life, obsidian is an extrusive igneous rock like andesite, meaning that they are both formed from lava that has cooled down.
  • Destroying an obsidian block with a diamond pickaxe while underwater without standing on solid ground would take 3 minutes and 54 seconds. (Without the pickaxe, it takes 4 minutes and 10 seconds.) Either way, the player will run out of air long before the block is mined. (Unless a potion of water breathing is used)
  • It is a common misconception that enough TNT will destroy obsidian. Even though its explosion resistance rating is finite, additional TNT or other explosives will have no more effect on an individual block than only one (it would take 71.25 times the explosive power of TNT to destroy a block of obsidian). It is possible to hack or use /summon an explosion strong enough to destroy obsidian, but no such explosion appears naturally.
    • The "Blue Wither Skull"'s ability to destroy obsidian is a special feature; its explosion is otherwise no stronger than a ghast's fireball.
