Combine Two Slabs Into a Full Block

Basic Crafting Recipe

The core mechanic of Slab Back Mod is simple: take any two slabs of the same type and combine them back into their original full block.

How to Combine Slabs

1. Open your crafting grid (2×2 inventory crafting or a crafting table)

2. Place two identical slabs in the grid—they must be the same material and type (e.g., two oak wood slabs, or two stone slabs)

3. The full block will appear in the output slot

4. Take the result and place it in your inventory

Important Notes

• Both slabs must match exactly in type and material
• The slabs do not need to be oriented the same way (top half vs. bottom half)
• This works with almost all vanilla slab types in the game
• You can combine slabs from any crafting surface—your inventory grid works just as well as a crafting table
