Obsidian is the hardest mineable block in Minecraft. It is found when flowing Water hits a Lava source block. If the water hits a moving Lava block, Cobblestone or Stone is produced instead. Obsidian is only obtainable with a Diamond Pickaxe or stronger. It takes 9 seconds to mine with even that. When Obsidian is mined with something other than a Diamond Pickaxe (or a diamond pickaxe underwater) it takes over four minutes and will not drop anything (the underwater diamond pickaxe is an exception to this). Obsidian is well known for its use in building Nether Portals. A 4x5 vertical rectangle of obsidian, hollow in the center, is required. Obsidian be found in all 3 dimensions.
