Nether Reactor Core

The Nether reactor core is an unused block that cannot be obtained within the creative mode inventory nor with the use of commands. They were formerly used to create Nether reactors in early versions of Pocket Edition before the addition of the Nether.

Nether reactor cores are currently unobtainable in new worlds except through inventory editing or add-ons. It is not available through commands or Creative. The block is, however, still usable for decoration in older worlds that had the block prior to it becoming unobtainable. In Survival mode, new Nether reactor cores cannot be crafted, including in worlds with the block, so once placed, the block would be lost if broken. In Creative mode it is still possible to use pick block control on existing Nether reactor cores to get the block into the inventory.

Mining a Nether reactor core using a pickaxe enchanted with Silk Touch yields the same drop as an unenchanted pickaxe. They drop 3 diamonds and 6 iron ingots.
