Wool

Wool is a block derived from sheep that can be dyed in any of the 16 different colors, which are white, orange, magenta, light blue, yellow, lime green, pink, gray, light gray, cyan, purple, blue, brown, green, red, and black.

Obtaining
Wool can be broken using any tool, but shears are the fastest.

Sheep
1 to 3 wool is harvested by shears on an adult sheep. If unshorn, sheep will drop 1 wool upon death. The wool dropped will be the same color as the sheep's wool. The drop rates are not affected by the Fortune or Looting enchantments.

White, light gray, gray, black, brown, and pink wool can be found naturally on sheep. The rest of the colors require dyeing sheep.

Natural generation


Black wool can also be found naturally in villages as part of a streetlight-like structure where they lie on top of three fence posts, surrounded by 4 torches. Various wool colors generate naturally as part of structures within woodland mansions.

Trading
Shepherd villagers sell each separate color of wool for a price of 1 to 2 emeralds for one wool as part of their tier 2 trades.

Usage
Wool blocks are weak, highly flammable, and offer little resistance against explosions. Their primary usage is as a decorative block.

Trading
Shepherd villagers buy 16 to 22 white wool for 1 emerald as part of their tier 1 trades.

Crafting ingredient

Fuel
Wool can be used as fuel in furnaces, smelting 0.5 items per wool block.
