Block of Iron is a solid metal block crafted from nine iron ingots, primarily used for storage, construction, and utility purposes.

It can be obtained through crafting, found in bastion remnants and trial chambers, and is mineable with a stone pickaxe or better. Blocks of iron are used to power beacons, spawn iron golems, and craft anvils. They also serve as a durable building material with a sleek metallic appearance. When placed under a note block, they produce an iron xylophone sound.
