The Nether Reactor Core is a Pocket Edition-exclusive block used in the Nether Reactor. It is very expensive to build, so it is very rare to be able to make one. Once activated by being surrounded by the proper amount of cobblestone and gold blocks, you activate the reactor by clicking on it (will tell you if in proper format or not), it temporarily transforms into Glowing Obsidian, then into a cube of Netherack.  


  • Making more than 1 is a waste because the core can be used again and again.
  • It can be used as a decoration.
  • Hitting the block when it is not placed in the correct Nether Reactor pattern will make a client message saying 'Not the correct pattern!'
  • On multiplayer, if you activate the Reactor when the players are out of range, it will say 'All players need to be close to the Reactor'. This is probably because of the way it skips day into night.
  • It is in no way related to the Nether biome.
  • If you destroy a Nether Reactor Core while it is activated it will drop 5 gold.
  • It has 3 stages; before activation, activation, and burnt out.
  • If you destroy it before it is finished, it will not finish (but items will still cease to spawn), and the glowing obsidian will stay there until you mine it away.
