Barrel

Barrels are tile entity storage blocks.

Obtaining
Barrels are currently only available from the creative inventory.

Usage
Barrels have the inventory of a chest. They do not have a GUI, but can be filled by droppers and both filled and emptied by hoppers. Barrels currently don't drop the items they contain when they are broken.

Block entity
A barrel has a block entity associated with it that holds additional data about the block.
