Overview
Dead Bubble Coral Block is an underwater block in Minecraft Java Edition 1.21.4. It has no crafting recipe — you collect it by mining it where it generates. Hardness 1.5 puts it in the middle of the pack for mining speed.
Mine it with a wooden pickaxe or better, or you get no drop at all. Broken correctly, it drops itself. Sixty-four fit in one inventory slot.
No recipe takes it as an ingredient.
How long it takes to break
Dead Bubble Coral Block has a hardness of 1.5. By hand that is 7.5 seconds per block; with the correct tool at netherite tier it is 0.25 seconds.
Iron takes 0.4 seconds against diamond's 0.3, so the upgrade worth making for this block is the one to diamond.
The block still breaks with a weaker tool, but below wooden it yields nothing at all — the time is spent and the drop is lost, which is the single most common way players waste a vein.
Efficiency adds its level squared plus one to the tool speed, so Efficiency V is about 2.5 times faster than the same tool unenchanted.
| Tool | No enchantment | Efficiency III | Efficiency V |
|---|---|---|---|
| Hand * | 7.5 s | 7.5 s | 7.5 s |
| Wooden | 1.2 s | 0.2 s | 0.1 s |
| Stone | 0.6 s | 0.2 s | 0.1 s |
| Iron | 0.4 s | 0.15 s | 0.1 s |
| Diamond | 0.3 s | 0.15 s | 0.1 s |
| Netherite | 0.25 s | 0.15 s | 0.1 s |
| Golden | 0.2 s | 0.15 s | 0.1 s |
Properties
With 6 blast resistance Dead Bubble Coral Block usually goes down to a nearby explosion. It is fully opaque and produces no light. 64 fit in a slot — a full stack. It is renewable, so one world can supply as much of it as you want. The block is tagged for pickaxes, and only that class gets the speed bonus; everything else mines at bare-hand rate.
