The Block Transformer is used to transform blcoks around itself.
The Block Transformer is created, by copying the image shown below in the TMC Crafter.
The Block Transformer turns diorite randomly every 30 seconds in a 5X5 area around itself. Diorite transforms into iron ore, coal ore, gold ore, lapis ore, redstone ore, diamond ore, emerald ore, quartz ore, cobblestone, stone, gravel, and back into diorite .
Diorite can transform into any of these blocks.
