Slab Back Mod FAQ

Place two slabs of the same type in a crafting grid (they can be arranged in any pattern) and you'll receive one full block back. Both slabs must match—you cannot mix different slab types in a single recipe.

The mod works with almost all block-slab combinations, including vanilla slabs and slabs from most other mods. If a slab type doesn't work, it's likely from a mod with unusual slab handling.

You need to use a crafting grid (crafting table, crafting bench, or player inventory crafting grid) to combine slabs—you cannot merge them by simply holding them together in your hotbar.

You can convert them back to full blocks by combining pairs of matching slabs in a crafting grid. This process can be repeated as many times as needed, though it will take time if you have a large quantity.

Yes, a top slab and a bottom slab of the same material will combine into one full block, making it easy to recover materials regardless of which slab variant you have.

The mod is lightweight and only adds a simple crafting recipe, so it should have no noticeable impact on performance or frame rate.

Yes, the mod is designed to work with slabs from most other mods, though compatibility depends on how those mods implement their slabs. Rare or heavily customized slab types may not work.

No, slab combining only works through crafting grids. Furnaces, hoppers, and other devices cannot process this recipe.

The recipe will not work—the crafting grid will not produce anything if the two slabs don't match. Both slabs must be made from the same block type.

Yes, you can use the standard Minecraft crafting recipe to convert any full block into slabs, just as you would without this mod. This mod only adds the ability to go from slabs back to blocks.
