Description

Gray Wool Slab is a half-height slab form of gray wool, added to Minecraft in Java Edition 26.3 and Bedrock Edition 26.40 after the Minecraft Live reveal on May 30, 2026. Placing three Gray Wool blocks in a horizontal row on the crafting grid yields six Gray Wool Slabs, and one stack holds 64 slabs of a single color. Each Gray Wool Slab has a hardness of 0.8 and breaks in 1.2 seconds by hand or 0.25 seconds with Shears.

Gray Wool Slab also blocks vibrations: a Sculk Sensor cannot detect placing, breaking, walking, sprinting, or jumping on Gray Wool Slab. A Gray Wool Slab placed between a Sculk Sensor and a vibration source stops the vibration from arriving. In Java Edition, one Gray Wool Slab smelts 0.25 items as Furnace fuel, so four slabs smelt one item. Three Gray Wool Slabs placed in a row craft one Gray Cushion, and any wool slab accepts a dye on the crafting grid to switch to another of the sixteen colors. Gray Wool Slab burns easily with a flammability of 30, ignites near lava, and resists explosions weakly at 0.8 in Java Edition and 0.16 in Bedrock Edition, so keep gray builds away from fire, lava, and explosions.

Guide

How to craft and use Gray Wool Slab in Minecraft

  1. 1

    Craft six slabs from three gray wool

    Place three Gray Wool blocks in a horizontal row on the crafting grid; the recipe produces six Gray Wool Slabs.

  2. 2

    Break slabs fast with Shears

    Break Gray Wool Slab with any tool; Shears clear one slab in 0.25 seconds, and a bare hand needs 1.2 seconds.

  3. 3

    Silence a Sculk Sensor

    Place Gray Wool Slab between a Sculk Sensor and a vibration source; the vibration cannot pass, and the Sculk Sensor never detects movement on Gray Wool Slab.

  4. 4

    Fuel a Furnace in Java Edition

    Load four Gray Wool Slabs into a Furnace as fuel to smelt one item, because one slab smelts 0.25 items in Java Edition.

  5. 5

    Craft one Gray Cushion

    Place three Gray Wool Slabs in a horizontal row on the crafting grid to craft one Gray Cushion.

One recipe family for sixteen colors

Crafting any wool slab with a dye re-dyes the slab to the dye's color, and all sixteen wool slab colors share the same crafting recipes.
