Overview
Dried Kelp Block counts as an underwater block in Minecraft 1.21.4. A crafting table turns its ingredients into Dried Kelp Block. It breaks almost instantly, with a hardness of just 0.5.
You can break it by hand without losing the drop. It drops as the same block you mined. With a blast resistance of only 2.5 it will not survive an explosion.
Sixty-four fit in one inventory slot. The recipe calls for Dried Kelp. It is not used in any crafting recipe.
How long it takes to break
Hardness 0.5 puts Dried Kelp Block at 0.75 seconds a block bare-handed, or 0.1 seconds with the right tool at netherite tier.
You are looking at 0.15 seconds on iron and 0.1 on diamond — the diamond step is where the time actually falls.
Nothing here needs a minimum tier: whatever you swing, the block still drops, and the only difference is how long it takes.
Efficiency adds its level squared plus one to the tool speed, so Efficiency V is about 2 times faster than the same tool unenchanted.
| Tool | No enchantment | Efficiency III | Efficiency V |
|---|---|---|---|
| Hand | 0.75 s | 0.75 s | 0.75 s |
| Wooden | 0.4 s | 0.1 s | instant |
| Stone | 0.2 s | 0.1 s | instant |
| Iron | 0.15 s | instant | instant |
| Diamond | 0.1 s | instant | instant |
| Netherite | 0.1 s | instant | instant |
| Golden | 0.1 s | instant | instant |
Properties
Blast resistance on Dried Kelp Block is 2.5, so any explosion nearby takes it out. It stops light entirely and gives off no light. Stack size is 64 — the standard full stack. Fire takes to it quickly — encouragement 60, burn 20 — which makes it a poor neighbour for lava or a lit campfire. The fastest tool for it is a hoe; any other kind of tool mines it no faster than a bare hand does, because the speed bonus only applies to the tool class the block is tagged for. As furnace fuel it burns for 200 seconds — 20 smelting operations.
