Overview
Bamboo Sign is one of the 12 variants of this shape in the game. What changes between them is the material, and with it the hardness, the drops, the durability and the recipe — so every figure on this page is this variant's own. Oak Sign is the same shape in a different material.
Bamboo Sign is a functional block in Minecraft Java Edition 1.21.4. Bamboo Sign is made at a crafting table. Hardness 1 puts it in the middle of the pack for mining speed.
No specific tool is required to collect it. Broken correctly, it drops itself. Because it is transparent it does not block light.
A blast resistance of 1 means a single creeper will clear it away. It stacks only to 16. You make it with Bamboo Planks and Stick.
No recipe takes it as an ingredient.
About the bamboo set
How long it takes to break
At a hardness of 1, Bamboo Sign takes 1.5 seconds to punch out and 0.2 seconds with a netherite-tier tool of the correct class.
You are looking at 0.25 seconds on iron and 0.2 on diamond — the iron step is where the time actually falls.
There is no tier requirement to worry about. Any tool, or none, returns the drop; the numbers below just say how fast.
The Efficiency formula is level² + 1 added to tool speed — at V that is about 4 times the unenchanted rate.
| Tool | No enchantment | Efficiency III | Efficiency V |
|---|---|---|---|
| Hand | 1.5 s | 1.5 s | 1.5 s |
| Wooden | 0.75 s | 0.15 s | 0.1 s |
| Stone | 0.4 s | 0.15 s | instant |
| Iron | 0.25 s | 0.1 s | instant |
| Diamond | 0.2 s | 0.1 s | instant |
| Netherite | 0.2 s | 0.1 s | instant |
| Golden | 0.15 s | 0.1 s | instant |
Properties
Bamboo Sign resists blasts at 1, which is not enough to survive anything explosive nearby. Light passes through it, and it emits none of its own. 16 fit in a slot. It is renewable, so one world can supply as much of it as you want. The fastest tool for it is an axe; 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 15 seconds — one and a half smelting operations.
