Dead Bubble Coral Block is the dried, greyed-out remnant of a live Bubble Coral Block, produced the moment a coral block loses access to water or is mined without the Silk Touch enchantment. The block carries hardness 1.5 and blast resistance 6, values shared with every coral family from the Update Aquatic (Java Edition 1.13, Bedrock 1.4.0), and a pickaxe is the only tool that drops Dead Bubble Coral Block as an item. Left standing on land, the dead block never revives and never decays further, so Dead Bubble Coral Block is the permanent, land-safe form of reef coral.

Builders reach for Dead Bubble Coral Block whenever a muted, fossilised coral tone is needed in dry builds where a live block would turn grey within seconds anyway. A full stack of 64 lets players stockpile Dead Bubble Coral Block by draining a farmed coral reef, and the block is fully renewable because live bubble coral generates anew in warm-ocean coral reefs. The greyish pattern reads as aged stone or petrified sponge in temples, ruins, and ocean monuments, pairing cleanly with prismarine and Dead Brain Coral Block without any water nearby.
