Forgebound Chests adds five upgradeable metal chests above the vanilla wooden chest. Start from a normal chest, then climb Copper → Iron → Gold → Diamond → Netherite. Each tier keeps your items, grows storage, and uses its own forged look.
Chest Tiers
| Tier | Grid | Slots | Notes |
|---|---|---|---|
| Copper | 9 × 6 | 54 | First step up from a wooden chest |
| Iron | 16 × 12 | 192 | Wide inventory |
| Gold | 16 × 48 | 768 | Tall storage, scroll to browse |
| Diamond | 16 × 192 | 3,072 | Very blast resistant |
| Netherite | 16 × 768 | 12,288 | Blast resistant and fireproof as an item |
Place two chests of the same tier side by side to make a double chest. The GUI shows up to 16 columns and 6 rows at a time, with a scrollbar for the rest.
Crafting
Copper through Diamond use the same glass-core pattern so they do not collide with vanilla “surround with 8 materials” recipes:
| Result | M | G | C |
|---|---|---|---|
|
Copper Chest |
copper ingot ×4 | glass ×4 | vanilla chest (or trapped chest) |
|
Iron Chest |
iron ingot ×4 | glass ×4 | Copper Chest |
|
Gold Chest |
gold ingot ×4 | glass ×4 | Iron Chest |
|
Diamond Chest |
diamond ×4 | glass ×4 | Gold Chest |
Netherite Chest uses tinted glass and 1 netherite ingot:
G = tinted glass · C = Diamond Chest · N = netherite ingot
In-world Upgrade
You can also upgrade a placed chest without emptying it. Hold the next tier's material in your main hand and right-click the chest. Contents and custom names are kept. Double chests cost twice as much. You cannot skip tiers.
