recycle your unwanted or worn-out tools, armor, slabs, stairs, and utility blocks back into their primary constituent materials

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

Mod loader

Minecraft version

⬇ Download for 1.21–1.21.11 · Fabric⬇ Download for 1.21–1.21.11 · Forge⬇ Download for 1.21–1.21.11 · NeoForge⬇ Download for 1.21–1.21.11 · Quilt
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

⚡ Recycle Your Gear. Reclaim Your Materials.

Reverse Crafting is a highly balanced, lightweight, and modern Minecraft datapack that lets you recycle your unwanted or worn-out tools, armor, slabs, stairs, and utility blocks back into their primary constituent materials—completely exploit-free!

Designed specifically for Minecraft 26.1 (Datapack Format 101), this pack integrates seamlessly into survival mode using vanilla mechanics like smelting, blasting, stonecutting, and shapeless uncrafting.

🛠️ Key Features

📖 How It Works

1. Smelting & Blasting

Recycle your metal weapons, armor, and utility items instantly. Blasting is twice as fast!

Input Process Output
Any Iron Equipment, Shears, Shield, Bucket, Compass, Cauldron, Minecart, Flint & Steel Smelting / Blasting 1x Iron Ingot
Any Gold Equipment, Clock Smelting / Blasting 1x Gold Ingot
Any Copper Equipment, Spyglass, Lightning Rod Smelting / Blasting 1x Copper Ingot
Any Netherite Equipment Smelting / Blasting 1x Netherite Ingot
Any Chainmail Armor piece Smelting / Blasting 1x Iron Ingot

[!NOTE] All smelting and blasting recipes have been set to instant smelting/blasting (0 seconds) for premium quality of life!

2. Shapeless Uncrafting

Place these items in any standard crafting grid to extract their key ingredients:

3. Slabs & Block De-compression

4. Stair Recutter

Put any stair block into a Stonecutter to safely slice it down into its base block form (1:1 conversion). Supported for all 40+ vanilla wood and stone stairs!

🔒 Anti-Exploit Design

[!IMPORTANT] Why is this pack safe for survival servers? Standard uncrafting packs usually return all materials used to craft an item. This introduces heavy duplication loops: players craft a pickaxe, use it until it has 1 durability left, and uncraft it to get all materials back, gaining infinite tools. Reverse Crafting avoids this by returning exactly 1 constituent item (the primary material) and discarding sticks/handles. Players are heavily penalized for uncrafting, making recycling useful only for unwanted loot or miscrafts, maintaining Minecraft's survival economy.

🚀 Installation Guide

  1. Download the datapack folder/ZIP file.
  2. In Minecraft, select your world, click Edit, and select Open World Folder.
  3. Open the datapacks directory and drop the mysterious-curie folder (or ZIP) inside.
  4. Open the world (or type /reload if you are already in the world) to load the recipes!
