Clay Barrel

The Clay Barrel is a block added by Ceramics. It can hold 4 buckets of a fluid, and can be expanded upwards with Clay and Porcelain Barrel Extensions. Barrel Extensions increase the capacity by 4,000 mB per block, and there is no limit to how many Barrel Extensions can be used on a single Barrel.

The Clay Barrel can output a redstone signal to a Redstone Comparator dependent on how full the Barrel is (including with Barrel Extensions). In the 1.11 and later versions of Ceramics, the level and fluid can also be determined by right clicking the barrel which will display as a message above the hotbar.
