Oxidized Copper Grate
Oxidized Copper Grate is the teal, fully weathered stage of the perforated copper panel added in Minecraft 1.21, see-through but solid, craftable from an Oxidized Block of Copper.
Description
Oxidized Copper Grate is transparent and perforated — players and mobs see through the holes, but entities cannot fall through and do not suffocate inside, mobs cannot spawn on top, and the block does not conduct redstone. Builders reach the oxidized teal tone either by crafting directly from an Oxidized Block of Copper, by letting an unwaxed Copper Grate weather through four stages over time, or by reversing the process with an axe or a lightning strike. Oxidized Copper Grate stacks to 64, can be waterlogged, and accepts a honeycomb to lock the weathered teal shade permanently — a practical choice for trial-chamber ruins, copper-themed factories, and industrial floors where a see-through, non-spawning surface is needed.

Java Edition Guide
How to get and use Oxidized Copper Grate in Minecraft
-
1
Craft four grates from copper blocks
Arrange four Oxidized Blocks of Copper in a 2×2 square on a crafting table to receive four Oxidized Copper Grates, or feed a single block to a stonecutter, which also yields four grates.
-
2
Mine with a stone pickaxe or better
Break Oxidized Copper Grate using a stone, iron, diamond, or netherite pickaxe; using any weaker tool or a bare hand drops nothing and wastes the block.
-
3
Lock the teal shade with a honeycomb
Right-click Oxidized Copper Grate with a honeycomb to wax the surface and freeze the oxidized teal colour permanently, preventing any further weathering change.
-
4
Build see-through, mob-safe floors
Lay Oxidized Copper Grate as a transparent ceiling or floor where light passes and mobs cannot spawn, then waterlog the block to let water flow through the perforations.
To strip Oxidized Copper Grate back to an earlier copper stage, right-click it with an axe — each use removes one oxidation layer. A lightning bolt that strikes the block directly clears all oxidation at once.

Frequently asked questions
Can you craft Oxidized Copper Grate directly?
Yes. Four Oxidized Blocks of Copper in a 2×2 crafting grid yield four Oxidized Copper Grates, and a stonecutter turns a single block into four — no weathering wait required.
What pickaxe do you need to mine Oxidized Copper Grate?
A stone pickaxe or better is required. Iron, diamond, and netherite pickaxes all work, but any weaker tool or a bare hand makes the block drop nothing.
Can mobs see through and spawn on Oxidized Copper Grate?
Mobs and players see through the perforations, but no mob spawns on top of Oxidized Copper Grate, and entities cannot fall through the holes or suffocate inside the block.
How do you stop Oxidized Copper Grate from changing further?
Right-click Oxidized Copper Grate with a honeycomb to wax the surface, which permanently locks the oxidized teal colour and prevents any further weathering.
Does Oxidized Copper Grate conduct redstone?
No. Oxidized Copper Grate is a transparent copper block and does not pass a redstone signal, so it cannot be used to extend redstone lines or power adjacent components.
Which version of Minecraft added Oxidized Copper Grate?
Oxidized Copper Grate was added with the Tricky Trials update, Minecraft Java Edition 1.21 and Bedrock Edition 1.21.0, released on 13 June 2024.
