Block of Iron

Blocks of Iron (also known as Iron Blocks) are decorative mineral blocks made from iron ingots which do not appear in normally generated maps anywhere. Iron blocks have the same texture on all six sides.

Iron blocks can be made by placing 9 iron ingots in a 3x3 square on a crafting grid. The 9 ingots can be recovered by placing the block in a crafting grid. This makes iron blocks more functional as "storage units" than as building units. Iron blocks can be mined with a stone, iron, or diamond pickaxe, taking about 2 seconds to destroy. If an iron block is mined without the use of a pickaxe, it drops nothing, wasting all 9 ingots.

Iron blocks and pumpkins are used to make Iron Golems in 1.2.
