Overview
In Minecraft 1.21.4, Cobweb is a building block. It has no crafting recipe — you collect it by mining it where it generates. Expect to wait: its hardness of 4 is well above average.
Mine it with a wooden sword or better, or you get no drop at all. Instead of dropping itself it yields String. Because it is transparent it does not block light.
A full stack holds 64. It is not used in any crafting recipe.
How long it takes to break
Cobweb has a hardness of 4. By hand that is 20 seconds per block; with the correct tool at netherite tier it is 0.7 seconds.
An iron tool takes 1 seconds and a diamond one 0.75, so the jump that actually matters for this block is the one to diamond.
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.
Efficiency adds its level squared plus one to the tool speed, so Efficiency V is about 3.5 times faster than the same tool unenchanted.
| Tool | No enchantment | Efficiency III | Efficiency V |
|---|---|---|---|
| Hand * | 20 s | 20 s | 20 s |
| Wooden | 3 s | 0.5 s | 0.25 s |
| Stone | 1.5 s | 0.45 s | 0.2 s |
| Iron | 1 s | 0.4 s | 0.2 s |
| Diamond | 0.75 s | 0.35 s | 0.2 s |
| Netherite | 0.7 s | 0.35 s | 0.2 s |
| Golden | 0.5 s | 0.3 s | 0.2 s |
Properties
Blast resistance on Cobweb is 4, so an explosion nearby will usually take it out. It lets light pass and gives off no light. Stack size is 64 — the standard full stack. The fastest tool for it is a sword; 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. Broken normally it drops String rather than itself; Silk Touch is what returns the block, and Fortune raises the ordinary drop instead.
