Clay is a block that can be found abundantly in lush caves, less commonly in shallow surface water or created from mud using pointed dripstone. It can be smelted into terracotta or broken into clay balls which are smeltable into bricks.
Clay blocks can be mined with any item, but shovels are quickest. Destroying a clay block yields 4 clay balls. If broken with a tool enchanted with Silk Touch, it drops itself instead. Destroying a clay block with a tool enchanted with Fortune does not increase the amount of clay dropped.
