In versions of Pocket Edition Alpha from 0.5.0 to 0.12.0, glowing obsidian was created when a nether reactor structure was active. The nether reactor's functionality has since been removed, leaving add-ons or inventory editors as the only remaining ways to obtain glowing obsidian.


Glowing obsidian has no purpose other than decoration and lighting up areas.


Pocket Edition Alpha
0.5.0Added glowing obsidian, generated from the conversion of blocks making up the reactor (nether reactor core, cobblestone, gold block) upon activation. Glowing obsidian could not be retrieved as a drop, instead regular obsidian was dropped. It took the same amount of time to mine as obsidian dropped upon mining using any pickaxe. Glowing obsidian was a solid block that emitted a light level of 12. Glowing obsidian emitted red smoke particles within close proximity to it so long as it existed, and it turned into obsidian after a short amount of time. It had the same blast resistance as normal obsidian.
If the nether reactor core was mined out while the nether reactor was active, the glowing obsidian wouldn't turn into obsidian after the reactor deactivated. This also caused the reactor to stop spawning items. If the gold blocks were mined out before they changed to glowing obsidian, the gold blocks were preserved, and the nether reactor continued spawning items.
0.7.1Wooden and stone pickaxes no longer make glowing obsidian yield obsidian.
0.7.3Glowing obsidian now requires a diamond pickaxe to mine (iron pickaxes no longer drop glowing obsidian).
0.8.0?Glowing obsidian no longer has red outline in the hotbar.
0.12.1build 1Glowing obsidian can no longer be obtained, though any existing blocks remain.
New Nintendo 3DS Edition
0.1.0Added glowing obsidian

  • Glowing obsidian makes an appearance in Minecraft: Story Mode - Season Two when Jesse places the structure block it spawns around the observer, and on the bottom of the obsidian cages Vos was in.
  • Glowing obsidian became unused when Silk Touch was added. Therefore, the block has never been obtainable.
  • Glowing obsidian has no name assigned to it, so its in-game name appears as[1]
    • Despite this, it can be assigned a custom name using resource pack with a language file.
