Terracotta

Hardened clay (Terracotta in Pocket Edition) is a block formed from clay, with a hardness and blast resistance comparable to stone. It can be stained in the same 16 colors that wool can be dyed, although the color is tinted orange.

Obtaining
Hardened clay can be mined using any pickaxe. If mined without a pickaxe, it will drop nothing.

Natural generation
Red, orange, yellow, brown, white, light gray and unstained hardened clay can be found naturally in mesa biomes. This yields a large quantity of hardened clay. Blue and orange hardened clay can also be found in desert temples.

Crafting
Once hardened clay has been dyed, the color cannot be changed or removed.

Building
Hardened clay has the same blast resistance as most other stone blocks, which is significantly higher than the block of clay before being smelted. A block of hardened clay when one meter away from an explosion will protect any blocks behind it, though it will be destroyed in the process.

Block data
Stained hardened clay has the ID name.
