Beacon in Minecraft: build the pyramid and pick the right power
Block of Iron, Block of Gold, Block of Emerald, Block of Diamond and Block of Netherite.

The Block of Iron holds nine Iron Ingot and also builds iron golems with a carved pumpkin and anvils. A storage block packs nine of a material into one block and turns back into nine at any time.
It is made with the Crafting Table from 9 × Iron Ingot. It is mined with a pickaxe (at least tier stone).
Craft nine items in a square to get the block, and the block alone back into nine items: nothing is lost, and a chest holds nine times more. Storage blocks need a pickaxe to drop, and the precious ones need at least iron.
Iron, gold, diamond, emerald and netherite blocks also form the base pyramid of a Beacon, one to four levels high.
9 × Iron Ingot → Block of Iron
// Slots with several items cycle through every accepted option.
Block of Iron, Block of Gold, Block of Emerald, Block of Diamond and Block of Netherite.
Craft a Mechanical Press (Shaft on top, Andesite Casing in the middle, Block of Iron below) and a Depot (Andesite Alloy + Andesite Casing, shapeless).
At the Crafting Table: 9 × Iron Ingot give 1 × Block of Iron. Mining the block drops it. It can be found as loot in Trial Chambers and Bastion Remnant.
It stores nine items in one block and decorates as a solid color. It is an ingredient in 2 recipes, made at the Crafting Table; for example Anvil and Iron Ingot.
The fastest tool is the pickaxe. It needs at least a stone pickaxe.
Placed under a Note Block, Block of Iron gives the Iron xylophone sound.
