Obsidian is the second strongest Block in Minecraft, and it is the strongest block that can be mined. It is only found near Lava beds below sea level, and is created when Water touches a still lava source, causing the lava source to turn into an Obsidian Block. For this reason, it is usually found very deep underground, by layer 10. However, it can still be found anywhere where water and lava meet. To mine Obsidian, a Diamond Pickaxe must be used, and it takes 9.375 seconds to mine, or quicker if the Pickaxe is enchanted with any level of Efficiency. It takes 250 seconds to mine by hand, and 50 seconds to mine with any pickaxe under Diamond, although neither will yield blocks of Obsidian.
Obsidian is renewable, as the obsidian spawning platform and Ender Crystal pillars in The End are regenerated by The Player reentering the dimension and respawning the Ender Dragon, respectively. It is also spawned when Nether Portals are created; the four extra corner blocks can be mined and used to create infinite nether portals (excluding world size).
Obsidian is also the only material that can be used to make a portal to The Nether, as of the October 31st Halloween Update. To make a portal, a frame made of Obsidian must be erected, standing 4 blocks long and 5 blocks high The maximum size is a square 23 by 23 high as of release 1.7, and the remaining space should be left open. The corner blocks need not be included in the rectangle. Then, the bottom Obsidian blocks should be lit on fire with a Fire Charge or Flint and Steel, though Lava will not work. After this is done, the portal opens, granting access to The Nether. Obsidian is also resistant to explosions, with the exception of the Wither's skeleton skull attack. Because of this fact, many players have constructed execution-by-TNT rooms out of Obsidian.
In addition to the TNT execution rooms, multiplayer servers find Obsidian to be the best defensive structure, as it is nearly impossible to destroy. Making a wall around a city in Obsidian may take a long time, but is well worth the defense when defending from an attack, especially since it renders TNT useless.

- While Obsidian is a strong block in Minecraft, Obsidian in real life is a fragile volcanic glass - but the mistake here comes from Obsidian not being harder than Diamond as well as for Obsidian to reach a sharpness equal to (if not, higher) than Diamond. It was for this reason that Obsidian was a popular material used for arrow tips.
- Changing the in-game language to Pirate will name the block "Rock o' Tears", possibly a reference to the unimplemented Crying Obsidian.
- Village blacksmith and Nether Fortress Chests sometimes come with obsidian, although three times as often in the former.
- It makes a great base/house if a player wants it there permanently.
- In Minecraft: Pocket Edition, Glowing Obsidian, a red glowing obsidian, can be created by activating a Nether Core Reactor. It cannot be mined and obtained.
