Green Terracotta is a dyed form of terracotta, crafted by placing 1 green dye in the center of a crafting grid and filling the other 8 cells with terracotta — the recipe outputs 8 Green Terracotta and is irreversible, so the green color can never be removed or changed. Unlike red, orange, yellow, brown, white, and light gray terracotta, Green Terracotta does not generate in the layered badlands terrain, which leaves crafting and villager trading as the practical sources. An expert-level mason villager sells all 16 terracotta colors, making Green Terracotta a renewable resource (a supply players can restock endlessly through trading). Green Terracotta requires a pickaxe to mine — a wooden pickaxe is enough — and drops nothing when broken without one.

Green Terracotta has a hardness of 1.25 and a blast resistance of 4.2, and neither catches fire nor suffers from lava, so flames and lava pools cannot burn a green wall away. Smelting Green Terracotta in a furnace produces Green Glazed Terracotta and grants 0.1 experience per block. The plain terracotta needed for the recipe comes from smelting clay blocks at 0.35 experience each, and one cactus smelted in a furnace yields the green dye at 1 experience on Java Edition. Green Terracotta stacks to 64. Builders reach for Green Terracotta when a roof, floor, or accent needs a green that fire cannot touch.
