The eleven crates

Eleven tiers, each nine slots larger than the one before, ordered by how deep the material sits rather than the usual iron-gold-diamond ladder. Each is the previous crate surrounded by eight blocks of the new material, except the first, which surrounds a chest of the game.

Crafting grid with a vanilla chest at the center, eight coal blocks in the surrounding slots, and a coal crate in the output slot. — First tier: a vanilla chest ringed by eight coal blocks turns into a coal crate.

Crafting grid with a gold crate at the center, eight amethyst blocks in the surrounding slots, and an amethyst crate in the output slot. — The rule holds further down the list: a gold crate ringed by eight amethyst blocks turns into an amethyst crate.

The eleven crates lined up on a platform, from coal to netherite, with a vanilla chest at the end of the row. — All eleven in order, with the vanilla chest at the end for scale.

The eleven tiers, and what it takes to reach the next
Crate	Around the previous one	Slots
Coal	block of coal, around a chest	27
Copper	block of copper	36
Iron	block of iron	45
Redstone	block of redstone	54
Lapis	block of lapis lazuli	63
Gold	block of gold	72
Amethyst	block of amethyst	81
Quartz	block of quartz	90
Emerald	block of emerald	99
Diamond	block of diamond	108
Netherite	block of netherite	117

The order follows how deep the material sits rather than the usual iron-gold-diamond ladder, which is why redstone and lapis slot in ahead of gold, and netherite, the deepest of all, closes the list.

Two crates that pair up

Two crates of the same tier placed side by side open one screen, the way vanilla chests do. The slots of both halves run on without a break, sorting treats them as one series, and the two share a single module: what sits on one half's tab counts for the whole pair.

A pair of netherite crates is therefore 234 slots, and 522 with sixteen row modules. Two different tiers side by side stay two separate crates.

What a crate keeps of its name

A crate renamed on an anvil keeps that name once placed, and the screen shows it in the top left. A name wider than the room available is cut before the page number rather than drawn over it.

Eleven double crates lined up on a platform, one per tier, from coal to netherite. — One double crate per tier. Each pair opens a single screen.

A renamed crate screen, the name cut before the page number in the top right. — A name too wide is cut before the page number, never drawn over it.

Breaking a full crate. The contents drop on the floor cut into stacks of 64, because that is all a ground stack can carry. A double netherite crate with a 512 module therefore returns well over a thousand stacks at once, and nobody picks that up before it despawns. Empty it before you break it.
