Glowing Obsidian

Glowing Obsidian is a block which only generates 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. It does indeed glow, but its physical properties are closer to Obsidian, as it requires a Diamond Pickaxe to break and takes the same amount of time, except instead of dropping itself, it drops a normal Obsidian block. The block will emit red smoke particles within close proximity to it so long as it exists, similar to the particles Redstone Dust creates when activated. Although in the Nether Reactor the block seems to spawn items around it, it is not the block itself that acts like this, nor will it spawn items if placed normally. The block turns into obsidian after a short amount of time. Otherwise it is simply an aesthetic block, as it has the same blast resistance as normal Obsidian. It is also possible to be mined with a wooden pickaxe.
