Horn Coral Block
minecraft:horn_coral_blockThe Horn Coral Block is a yellow decorative block that generates naturally in coral reefs within warm ocean biomes. It must stay adjacent to water or it dries into a dead coral block within a few seconds, so it can only be collected with a Silk Touch tool.

No, once a coral block dries out and turns into its dead variant, the transformation is permanent.
What is the Horn Coral Block used for?
