Block of Iron

Blocks of Iron (also known as Iron Blocks) are blocks for storing iron ingots that do not appear in normally generated maps anywhere. Iron blocks have the same texture for each of its sides.

Iron blocks can be made by placing 9 iron ingots in a crafting bench. 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 broken without such a tool, it drops nothing, wasting all 9 ingots.

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

History
In Survival Test, breaking iron ore would cause 1 - 3 iron blocks to drop.

Iron blocks had a different skin when first made, using three different textures. The texture was changed from to  in the Halloween Update.

In Classic it is still seen as. This block used three textures instead of one.

In Beta 1.9 Pre-release 5, the texture was changed again, now having subtle lines (corrugations) through it.
