Overview
In Minecraft 1.21.4, Horn Coral Block is an underwater block. There is no way to craft it; you have to find it and mine it. Its hardness of 1.5 makes it a normal, unhurried block to mine.
Anything below a wooden pickaxe breaks it without leaving a drop. Breaking it produces Dead Horn Coral Block. It stacks to 64.
Nothing on the crafting grid is made from it.
How long it takes to break
Horn Coral Block sits at hardness 1.5: 7.5 seconds per block with your fists, 0.25 with the correct netherite tool.
Iron manages 0.4 seconds and diamond 0.3, which makes diamond the tier that changes how this block feels.
A weaker tool still breaks it, but anything under wooden returns nothing — you spend the time and lose the drop, which is how most veins get wasted.
Each Efficiency level adds level² + 1 to the tool's speed, so a level V tool clears this about 2.5 times faster than an unenchanted one.
| 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 Horn Coral Block usually goes down to a nearby explosion. It is fully opaque and produces no light. Stack size is 64 — the standard full stack. It renews, so a single world will never run out. A pickaxe is the fastest choice here. A tool of the wrong class is no better than your fist — the speed bonus is tied to the block's own tool tag. Broken normally it drops Dead Horn Coral Block rather than itself; Silk Touch is what returns the block, and Fortune raises the ordinary drop instead.
