Overview
Brain Coral Block is an underwater block in Minecraft Java Edition 1.21.4. 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 Brain Coral Block. It stacks to 64.
Nothing on the crafting grid is made from it.
How long it takes to break
Brain 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.
You are looking at 0.4 seconds on iron and 0.3 on diamond — the diamond step is where the time actually falls.
Below wooden the block breaks and simply vanishes. Bring the right tier or leave it in the ground.
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 Brain 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. Broken normally it drops Dead Brain Coral Block rather than itself; Silk Touch is what returns the block, and Fortune raises the ordinary drop instead.
