Description

Blue Wool is the dyed form of Minecraft wool, crafted from any wool block and a blue dye. Sheep never spawn blue — natural sheep colors run white, black, brown, light gray, gray, and rarely pink — so players create Blue Wool by dyeing. Right-click a sheep while holding a blue dye, then use shears on the adult sheep to collect 1–3 Blue Wool; shears also break placed wool the fastest. Blue Wool additionally generates naturally in ancient cities alongside cyan and light blue wool, a feature introduced in Java 1.19.

Blue Wool serves builders as a bright blue block and crafts into blue beds (beds require wool of one matching color), blue carpets, blue banners, and paintings made from any wool color. A wool block placed between a sculk sensor and a vibration source blocks that vibration, and sculk sensors cannot detect Blue Wool being placed, broken, or walked on. Blue Wool ignites easily, resists explosions barely, stacks to 64 blocks of one color per slot, and smelts 0.5 items per block as furnace fuel in the Java Edition.

How to get Blue Wool in Minecraft

    Craft Blue Wool from any wool

    Place any wool block together with a blue dye on the crafting grid to receive one Blue Wool block.

  2. 2

    Dye a sheep, then shear it

    Right-click a sheep while holding a blue dye, then use shears on the adult sheep to collect 1–3 Blue Wool.

  3. 3

    Visit an ancient city

    Search ancient city structures, where Blue Wool generates naturally alongside cyan and light blue wool.

    Open a shepherd villager's trade menu and buy wool of any color, Blue Wool included.

Blue Wool hides from sculk sensors

Sculk sensors cannot detect Blue Wool being placed, broken, or walked on, and a Blue Wool block placed between a sensor and a vibration source blocks that vibration entirely.

Frequently asked questions

Can Blue Wool be re-dyed into another color?

Yes. Wool of any color can be re-dyed into any other color on the crafting grid, so a Blue Wool block plus any dye gives the wool of that dye's color.

Is Blue Wool renewable?

Yes. Sheep drop wool of their own color, so one sheep dyed blue yields 1–3 Blue Wool per shearing and 1 Blue Wool if killed un-sheared.

How many wool colors exist in Minecraft?

Sixteen. White wool is the undyed base block and the other fifteen colors, Blue Wool included, are dyed variants.

Does Blue Wool work as furnace fuel?

In the Java Edition, yes: one wool block smelts 0.5 items in a furnace. The fuel use is a Java Edition feature.
