You may have thought that copper blocks are diverse enough and don’t really need to be expanded. Well, Mojang strongly disagrees with that. The Minecraft 1.21 update brings five more copper blocks that are all unique in their own way. Today we’ll take a look at one of these new blocks, a Copper Grid, and discuss its recipe and uses in Minecraft 1.21. So, without further delay, let’s get started right away!
Copper grid is a decorative block from the copper block family. It goes through all 4 stages of oxidation, can be waxed with honeycomb and can be scraped with an axe. In addition, it has some similarities with the glass block, as they allow light to pass through completely.

What you need to make a copper grille
Because there are two ways to make copper grilles, the requirements are slightly different. The copper grids require at least 4 copper blocks when using the crafting table or at least 1 copper block to make them using a stonemason.
You can making copper blocks with nine copper blocks completely filling the 3×3 crafting grid. The copper blocks you use to make the grids can be at any stage of oxidation, but make sure you only use blocks from the same stage.
Minecraft 1.21 Copper Grids: Crafting Recipe
First we will show you the steps to make copper grilles using a crafting table and then using the stonemason. So, after you have collected the raw materials, choose the way you want to make the copper grilles and follow the steps below.
Method 1: Using a Crafting Table or Crafter
- Place the crafting table or the crafter in your world. Then right-click on it to open the block’s user interface.
- Now you need to place 4 copper blocks in a diamond shape. Start by placing one of them in the middle slot of the top row of the grid.
- Then place the second copper block in the center slot of the bottom row of the grid.

- Then you need to place copper blocks in the middle slot of the left and right columns.
- And that’s it. You have successfully created four copper grids in the game.

If you use one tinkerer in Minecraft, you need to power it with a redstone signal to get the copper grids. You can use a button, lever or even a redstone block for this.
Method 2: Using a stonemason
- Place the stonemason in your world and right-click to open the user interface.
- As you can see, it is different from the regular crafting grid. What you need to do here is insert a copper block into the input slot on the left.
- You can then select the copper grid block that appears in the central part of this UI.
- And that’s it. You can now click on the copper grid block on the right and move it to your inventory.

Where can you find copper grilles in Minecraft?
As with other copper blocks added in the Minecraft 1.21 update, copper grids are generated naturally in the tasting rooms. They are massive underground structures with procedurally generated rooms. Moreover, they are meant to represent exciting combat challenges, and therefore expect many dangers within.
As of this writing, we don’t know much about the Trial Chambers or which biome they spawn in. But once we do, we’ll update this article so you know exactly where to find these cool blocks.
How to use copper grilles in Minecraft 1.21
Copper Grids only have one function in the game, at least so far, and that is to improve your Minecraft builds as much as possible. Have these building blocks four different textures for each oxidation phase, just like all other copper blocks. So for the price of one we received a total of four beautiful blocks.

The copper lattice in one of the first three stages will slowly oxidize over time, changing its color from orange to green. You can easily stop this process by right-clicking on the grid honeycomb. This will freeze its stage and appearance. Alternatively, you can make the waxed version of this block by combining it with the honeycomb item in the crafting grid.

If you might want to reset the grid block one oxidation stage, you can do so by right-clicking on it with an axe. However, if you have already applied honeycomb to the copper grid, simply scrape off the wax with an ax and allow the block to further oxidize if it has not yet reached the final stage.

As we already mentioned, copper grilles have a number of special properties. They are transparent blocks, which means they leave the light on whole pass. Additionally, enemy mobs cannot spawn on top of the grid blocks. This makes copper grids useful on farms or for spawning an area.
Moreover, a gang trapped in the copper grate block will not suffocate. This feature is more practical than you think because it ensures that the crowd is safe and quiet in a certain place. Another notable fact about the copper grids is that they cannot conduct redstone signals, which is also a property of glass blocks.
Congratulations! Now you know everything about the new copper grid block. In short: they are beautiful new building blocks that will make the dreams of many Minecraft builders come true. Copper Grilles could potentially become the next best window blocks in the game. We really can’t wait to see what the community will create with them.
