Overview#
Iron Chests expands Minecraft's single, cramped wooden chest into a full ladder of upgraded chests with progressively more storage. Build up from copper and iron to gold, diamond, crystal, and obsidian, each holding many more items than the last. The crystal chest is transparent and even shows its contents from the outside, and obsidian chests are tough and blast-resistant.
Best of all, you never have to empty a chest to upgrade it: upgrade items convert a chest to the next tier in place, keeping everything inside.
Getting Started#
- Craft a tiered chest directly, or craft a vanilla chest first and then apply an upgrade to raise it a tier (see Upgrades).
- Place it and use it like any chest. Each tier simply offers more slots.
Check the in-game recipe book for the exact crafting and upgrade recipes for each tier.
Chest Tiers#
Each tier holds more than the last (a vanilla chest holds 27 slots for comparison). Typical Iron Chests progression:
| Tier | Notes |
|---|---|
| Copper | The first step up from a vanilla chest - more rows of storage. |
| Iron | A solid mid-tier upgrade with a large slot count. |
| Gold | More storage again, the common "main base" chest. |
| Diamond | Very large capacity for bulk storage. |
| Crystal | The largest standard capacity and transparent - you can see the items stored inside. |
| Obsidian | Extremely durable and blast-resistant, ideal for protecting valuables from explosions. |
Higher tiers add more rows/columns of slots, so a single diamond or crystal chest can replace several vanilla chests.
Upgrades#
The upgrade items are the heart of the mod's convenience.
- Each upgrade converts a chest from one specific tier to the next (e.g. a Copper-to-Iron upgrade, an Iron-to-Gold upgrade, and so on, up to crystal/obsidian).
- Right-click an existing chest with the matching upgrade to transform it in place - all stored items stay exactly where they are. No need to move your inventory out first.
- This lets you start with a cheap chest and progressively invest in it as you gather better materials, without ever interrupting your storage.
Use the recipe book to see which upgrade leads from each tier to the next.
Tips#
- Upgrade in place instead of emptying chests - it is faster and risk-free.
- Use crystal chests where you want to see contents at a glance (sorting rooms, display walls).
- Use obsidian chests for anything you cannot afford to lose to a creeper or other explosion.
- Mix tiers: cheap copper/iron for bulk junk, diamond/crystal for valuables.
Troubleshooting & FAQ#
Will upgrading lose my items? No - upgrade items convert the chest in place and keep all contents.
Why is the crystal chest see-through? That is intentional - it visually shows what is stored inside.
Which chest is biggest? The crystal chest has the largest standard slot count; obsidian trades some capacity considerations for durability and blast resistance.
Can I craft a high-tier chest directly, or must I upgrade? Both - you can craft tiers directly or climb the ladder with upgrades, whichever your materials favor.
