Waxed Exposed Copper Bulb — Minecraft block

Overview

Waxed Exposed Copper Bulb is a building block in Minecraft Java Edition 1.21.4. A crafting table turns its ingredients into Waxed Exposed Copper Bulb. Its hardness of 3 makes it a normal, unhurried block to mine.

Anything below a stone pickaxe breaks it without leaving a drop. It drops as the same block you mined. It stacks to 64.

You make it with Waxed Exposed Copper, Blaze Rod, and Redstone Dust. No recipe takes it as an ingredient.

How long it takes to break

Hardness 3 puts Waxed Exposed Copper Bulb at 15 seconds a block bare-handed, or 0.5 seconds with the right tool at netherite tier.

An iron tool takes 0.75 seconds and a diamond one 0.6, so the jump that actually matters for this block is the one to iron.

The block still breaks with a weaker tool, but below stone it yields nothing at all — the time is spent and the drop is lost, which is the single most common way players waste a vein.

The Efficiency formula is level² + 1 added to tool speed — at V that is about 3.3 times the unenchanted rate.

Properties

Waxed Exposed Copper Bulb resists blasts at 6, which usually is not enough when something explodes nearby. Light does not pass through it, and it emits none of its own. One inventory slot holds 64, the normal full stack. A pickaxe is fastest here; any other class mines it at bare-hand speed, because the bonus only applies to the class the block is tagged for.
