Once the pattern is built, all players must stand within a certain range of the Nether Reactor. If the pattern is somehow incorrect, there will be a text message that just says "Incorrect pattern!". Once it is hit (while it is in the correct pattern), a text message that says "Active!" will pop up, and the Nether Spire will be formed around it. The Cobblestone will then change to Glowing Obsidian , which is a red obsidian -like block. After a while, the Gold Blocks will too become glowing Obsidian. Before they do though, you may mine them for reusing. While the Reactor is active, it will spurt out many items and blocks , as well as spawning Zombie Pigmen . The Zombie Pigmen are naturally hostile to you. After 45 seconds, the Reactor will stop spawning items and Zombie Pigmen . Holes in the Nether Spire will appear, and all the Glowing Obsidian will become normal Obsidian . The core will then become a dull blue, and can be mined and reused.
These are diagrams of how to set up the Nether Reactor to activate it, not crafting recipes.
