Horn Coral
minecraft:horn_coralHorn Coral is a non-solid decorative block that naturally generates in coral reef structures found in warm ocean biomes. It breaks instantly when mined, but must be harvested with a Silk Touch tool to keep its living form, since it dies and turns into dead coral within seconds if it loses contact with water.
FAQ
How do I collect Horn Coral without it dying?
You must mine it with a tool enchanted with Silk Touch; otherwise it drops nothing, and any placed coral not touching water converts to dead coral within 3-10 seconds.
Where does Horn Coral generate?
It generates naturally within coral reef structures found in warm ocean biomes, alongside tube, brain, bubble, and fire coral variants.
Can I grow more Horn Coral?
Yes, it is renewable — applying bone meal to suitable substrates like dirt, sand, gravel, or clay in a warm ocean biome can generate new coral.
When did Horn Coral become obtainable in Survival?
Although teased as early as 2009, it remained technically unobtainable until Silk Touch harvesting was added in Java Edition 1.13-pre10.
