Glowing Obsidian

Glowing obsidian is an unobtainable block that has no use, other than decorating.

Obtaining
Glowing obsidian can be mined with a diamond or netherite pickaxe, or it drops nothing. If mined with the proper tool, the block drops itself.

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, or retaining the block from previous worlds. It is not in the player's Creative inventory and cannot be obtained using commands.

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

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