Nether Reactor Core

The nether reactor core was an unused block that couldn't be obtained with the use of commands.

Obtaining
Nether reactor cores were currently unobtainable in new worlds except through inventory editing or add-ons. It was not available through commands or Creative. The block was, however, still usable for decoration in older worlds that had the block prior to it becoming unobtainable. In Survival Mode, new Nether Reactor Core couldn't be crafted, including in worlds with the block, so once placed, the block would be lost if broken. In Creative Mode it was still possible to use Pick Block on existing Nether Reactor Cores to get the block into the inventory.

Breaking
Mining a nether reactor core using a pickaxe enchanted with Silk Touch yielded the same drop as an unenchanted pickaxe. They dropped 3 s and 6 s.

Usage
Nether reactor cores could be used for decoration.
