Barrels are a block which allow simple liquid storage. Barrels come in two types:

• Clay barrels: Available in the normal clay color and the 16 stained colors. Has a capacity of 4 buckets by default.
• Porcelain barrels: Available in the 16 porcelain colors. Has a capacity of 6 buckets by default.

Barrels can be extended by placing an extension on top. Each extension will add an additional amount to the capacity of the barrel, with 4 buckets added for clay extensions and 6 buckets added for porcelain extensions. Additionally, extensions can be interacted with as if they were the based of the barrel, treating all parts as the same tank. Colors can be mixed, but clay and porcelain barrels and extensions cannot be mixed.
