Nether Reactor Core

The Nether Reactor Core is a block. It is the main component in constructing the Nether Reactor. It is the only way to obtain Glowstone, Nether Quartz and Melon in-game as of 0.6.0.

Crafting
Crafting the Nether Reactor Core requires three diamonds and six iron ingots.

Usage
(please improve) the nether reactor core creates a kind of nether "room" which obsidian and netherrack forms around. It spawns zombie pigmen, items, glowing obsidian, and netherrack, which gives players all the resources of the nether without actually going there.
