Metal Barrels in FTB StoneBlock 4

Metal Barrels is a storage mod that gives you bigger versions of the vanilla barrel. If you're tired of chest walls or want a compact way to hold lots of items, this is for you. This pack includes version 7 of the mod.^[1][2]

The barrels work like their vanilla counterparts: you can open them even with a solid block on top. Unlike chests, they don't cause FPS issues in large numbers, so you can build big storage rooms without your game slowing down.^[1]

Barrel tiers

• Copper stores 45 stacks.^[1]
• Iron stores 54 stacks.^[1]
• Silver stores 72 stacks.^[1]
• Gold stores 81 stacks.^[1]
• Diamond stores 108 stacks.^[1]
• Crystal also stores 108 stacks and is transparent, so you can see what's inside.^[1]
• Obsidian stores 108 stacks and has the blast resistance of obsidian, which makes it resistant to most explosions.^[1]
• Netherite stores 135 stacks and has the fire and blast resistance of netherite.^[1]

Upgrading barrels

The mod has upgrade items that let you upgrade a barrel that's already placed, without breaking it. The contents are not destroyed or dropped when you use one.^[1]

Unverified Where Metal Barrels fits in this pack's progression, and whether the pack changes any of the mod's recipes or values, isn't confirmed by the available sources. Check the recipe viewer in game before you plan around a specific tier. This site does hold FTB StoneBlock 4's own recipes, read from the pack itself: look the item up in the item browser.

Metal Barrels gives you bigger versions of the vanilla barrel. They open the same way, with a solid block on top, and the mod page says they don't cause FPS issues in large numbers the way chests can. Here's the order I'd go in.^[1]

Make your first metal barrel

Your entry point is a plain wooden barrel. The pack gives you two ways to turn one into a metal barrel. The first gives you a Copper Barrel, which holds 45 stacks.^[1][3]

Upgrading barrels you've already placed

You don't have to break a full barrel to upgrade it. The mod has upgrade items, and the mod page says the contents are not destroyed or dropped when you use one. Items like Copper To Iron are named after the two tiers they connect.^[1][3]

There is also a crafting version of each upgrade. It combines the upgrade item with a barrel of the matching starting tier to give you the next barrel.^[3]

Metal Barrels is a simple storage mod, so there are no power, fluid or multiblock systems to learn. It adds tiers of barrels that hold more than vanilla ones. They work like vanilla barrels: you can open them with a solid block on top. The mod page also says they don't cause FPS issues in large numbers, unlike chests.^[1]

Storage capacity by tier

Here is what the mod's project page lists for each tier, measured in stacks.^[1]

• Copper Barrel: 45 stacks.^[1][3]
• Iron Barrel: 54 stacks.^[1][3]
• Silver Barrel: 72 stacks.^[1][3]
• Gold Barrel: 81 stacks.^[1][3]
• Diamond Barrel: 108 stacks.^[1][3]
• Crystal Barrel: 108 stacks, and it is transparent.^[1][3]
• Obsidian Barrel: 108 stacks, with a blast resistance equivalent to obsidian, so it resists most explosions.^[1][3]

Upgrading barrels

You don't have to break and replace a barrel to move up a tier. The mod has upgrade items that work on barrels you've already placed, and the contents are neither destroyed nor dropped when you use one.^[1]

The upgrade items are named for the tier they start from and the tier they reach, such as Wood To Copper, Copper To Iron and Gold To Diamond. The pack also has crafting recipes that combine upgrades into longer jumps, like Wood To Diamond. Two of them are shown below.^[3]

Metal Barrels works as a ladder of tiers. The tiers in the recipes are wood, Copper Barrel, Iron Barrel, Silver Barrel, Gold Barrel, Diamond Barrel, Crystal Barrel, Obsidian Barrel and Netherite Barrel. In this pack you climb it with direct barrel recipes or with upgrade items.^[3]

Direct barrel-to-barrel steps

These are the single-step recipes that turn one barrel into the next tier. Each one has its own crafting recipe in the pack.^[3]

• A Copper Barrel upgrades to an Iron Barrel.^[3]
• An Iron Barrel upgrades to either a Silver Barrel or a Gold Barrel.^[3]
• A Silver Barrel upgrades to a Gold Barrel or a Diamond Barrel. A Gold Barrel upgrades to a Diamond Barrel.^[3]
• A Diamond Barrel is the branching point: it upgrades to a Crystal Barrel or to an Obsidian Barrel.^[3]

The Netherite step

The top of the ladder is the Netherite Barrel. The recipe that makes it from an Obsidian Barrel is a smithing recipe, and it is marked as changed by the pack. The sources here do not show the mod's default, so use the recipe below as the truth for this pack.^[3]

The Wood To Copper upgrade item is one of the directly craftable ones.

The longer jumps, such as Wood To Diamond, Wood To Obsidian and the various upgrades to Netherite, exist as items and have combine recipes that turn the matching barrel into the target tier. Several of the long wood upgrades can also be built by combining shorter upgrades in a chain. For example, Wood To Iron, Iron To Gold and Gold To Diamond together make Wood To Diamond.^[3]

Unverified The sources here show no quests involving Metal Barrels, so the pack's quest book gives no guided order for this mod. The order above comes from the recipes alone.

There isn't much version history to tell for this mod. FTB StoneBlock 4 1.21.0 ships Metal Barrels 7 (file metalbarrels-neoforge-1.21.1-7.jar), and it has been in the pack since 1.0.0 or earlier.^[2]

The Metal Barrels 7 changelog doesn't list any changes, and there are no pack changelog entries for this mod. That means there are no notable changes between releases to point out.^[4]
