Glowing Obsidian

Glowing obsidian is an unobtainable decorative block that emits light.

Obtaining
Glowing obsidian drops itself only when mined with a diamond pickaxe or netherite pickaxe; otherwise, it drops nothing.

In Pocket Edition Alpha versions 0.5.0 through 0.12.0, glowing obsidian was created when a nether reactor structure was active. As the nether reactor's functionality was removed in version 0.12.1, add-ons or inventory editors are the only ways to obtain glowing obsidian in subsequent versions. It is not in the player's Creative inventory and cannot be obtained using commands.

Light
Glowing obsidian emits a light level of 12.

Issues
Glowing obsidian is an unsupported block, and as such, issues relating to them may not be fixed.
