Overview
Prismarine Slab is one of the 30 variants of this shape in the game. What changes between them is the material, and with it the hardness, the drops, the durability and the recipe — so every figure on this page is this variant's own. Oak Slab is the same shape in a different material.
Prismarine Slab is an underwater block in Minecraft Java Edition 1.21.4. Prismarine Slab has a crafting recipe, so it is renewable as long as you can source its ingredients. At a hardness of 1.5 it takes a moment to break but never slows a build down.
It needs at least a wooden pickaxe to drop anything; a weaker tool destroys it for nothing. Mining it returns the block itself, so it is safe to relocate. A full stack holds 64.
It is crafted from Prismarine. The stonecutter is the cheaper route: one Prismarine gives one of these. No recipe takes it as an ingredient.
About the prismarine set
How long it takes to break
Prismarine Slab sits at hardness 1.5: 7.5 seconds per block with your fists, 0.25 with the correct netherite tool.
Iron manages 0.4 seconds and diamond 0.3, which makes diamond the tier that changes how this block feels.
The block still breaks with a weaker tool, but below wooden it yields nothing at all — the time is spent and the drop is lost, which is the single most common way players waste a vein.
The Efficiency formula is level² + 1 added to tool speed — at V that is about 2.5 times the unenchanted rate.
| Tool | No enchantment | Efficiency III | Efficiency V |
|---|---|---|---|
| Hand * | 7.5 s | 7.5 s | 7.5 s |
| Wooden | 1.2 s | 0.2 s | 0.1 s |
| Stone | 0.6 s | 0.2 s | 0.1 s |
| Iron | 0.4 s | 0.15 s | 0.1 s |
| Diamond | 0.3 s | 0.15 s | 0.1 s |
| Netherite | 0.25 s | 0.15 s | 0.1 s |
| Golden | 0.2 s | 0.15 s | 0.1 s |
Properties
Blast resistance on Prismarine Slab is 6, so an explosion nearby will usually take it out. It stops light entirely and gives off no light. Stack size is 64 — the standard full stack. The fastest tool for it is a pickaxe; any other kind of tool mines it no faster than a bare hand does, because the speed bonus only applies to the tool class the block is tagged for. As furnace fuel it burns for 7.5 seconds — 0.8 smelting operations.
