Glowing Obsidian

Glowing Obsidian is a block, exclusive to the Pocket Edition. This block does not naturally generate, and appears only when the Nether Reactor is activated. Upon activation, the blocks that make up the reactor turn into Glowing Obsidian.

Properties
Glowing Obsidian is a solid block that gives off light similar to Glowstone Block, but slightly dimmer. Although glowing obsidian glows, it's physical properties are closer to Obsidian as it requires a Diamond Pickaxe to break and takes the same amount of time, it also drops a single Obsidian block. The block will emit red smoke particles close to it as long as it exists. Although in the Nether Reactor the block seems to spawn items around it, simply placing it in the world does not allow it to act like this.
