Slab Machines FAQ

Most slab blocks are crafted by placing the full-sized version in a crafting grid, which yields two slab variants. For example, one furnace becomes two furnace slabs. Some slabs like the crafting table require specific ingredients like wooden planks arranged around a furnace instead.

Yes, slab blocks function identically to their full-sized counterparts—they smelt, craft, store items, and produce sounds the same way. The only difference is they take up half a block space, letting you fit more workstations into compact builds.

No, in newer versions of the mod you cannot mix different slab types in a single block space. Each location can only contain one type of slab block.

No, slab blocks are fully compatible with performance mods like Fast Workbench and Fast Furnace, so they won't cause lag even in heavily optimized setups.
