How to oxidize Copper blocks in Minecraft

Let the air do the work.

In Minecraft, oxidizing any of the Copper blocks slowly transforms them from their orange-ish hue to a beautiful blue-green. I'll teach you how to oxidize Copper blocks, how to prevent them from oxidizing, and what the oxidized versions of Copper blocks look like in Minecraft.

How to change the color of Copper Blocks in Minecraft

All Copper Blocks have four levels of oxidation:

  • Regular (not oxidized)
  • Exposed (slightly oxidized)
  • Weathered (moderately oxidized)
  • Oxidized (fully oxidized)

To oxidize Copper Blocks, you only need to place them on the ground and wait. It is a pretty effortless process, but there are efficient and inefficient ways of going about it. If you want your Copper Blocks to oxidize faster, you'll need to space them further apart like those in the yellow circle in the image below. Each of these Copper Blocks has four blocks of space between it and the nearest Copper Block. The blocks in the blue circle are grouped, which makes them oxidize more slowly.

Not long after placing these blocks, I noticed that the rightmost two in the spread-out section had already turned into Exposed Copper Blocks. In contrast, none of the blocks in the grouped section had changed.

As time went on, the top right block transformed into a Weathered Copper Block. Finally, the bottom center block in the grouped section has oxidized slightly.

In the end, only one block in the grouped section oxidized to the first level. One did not oxidize in the separated level, another oxidized to the Exposed level, three to the Weathered Level, and one even completely oxidized.

This process can take a while, especially if you're planning to create a copper-based build. If you need a lot of regular and oxidized copper, I recommend exploring and mining through nearby Trial Chambers to get some quickly.

How to stop a Copper block from oxidizing in Minecraft

If you want to use a specific oxidation level of copper clocks in a build, you don't have to live in fear of them changing and ruining your creation. Instead, they can be locked into their current oxidation level using Honeycomb. This can be done by combining the block you want to lock in its oxidization stage with the Honeycomb on a crafting table. It will become a Waxed version of the block and will no longer oxidize.

This can also be done by interacting with any copper block while holding onto a piece of Honeycomb. You will know the block has become waxed when orange sparkles emit from it.

Every oxidized Copper block in Minecraft

Every type of copper block introduced in the Tricky Trials update can be oxidized, including doors and trapdoors. I'll explain the crafting recipes for each block and what they look like when oxidized.

Copper Blocks

Copper Blocks can be used like any other building block. They're crafted by filling all 9 blocks in a crafting table with Copper Ingots. As they oxidize, they become increasingly more green.

Chiseled Copper

Chiseled Copper is a more decorative version of the Copper Block. To craft it, you'll need four Copper Blocks. Place the four Copper Blocks in a 2x2 square in any crafting interface to produce four Chiseled Copper blocks.

Cut Copper Stairs

Cut Copper Stairs can be placed and used like all other Minecraft stairs. They are crafted using the same recipe and six Chiseled Copper blocks. This recipe produces four Cut Copper Stairs.

Cut Copper Slabs

Like Cut Copper Stairs, Cut Copper Slabs are identical to the other slabs in the game. Three Chiseled Copper can be used to produce six Cut Copper Slabs.

Copper Bulbs

Copper Bulbs are the newest light source block in Minecraft. Like Redstone Lamps, they need to be given Redstone power to turn on. They are crafted using three Copper Blocks, one Blaze Rod, and one Redstone.

The amount of light Copper Bulbs emit depends on their oxidation level:

  • Normal Copper Bulbs: Light Level 15
  • Exposed Copper Bulbs: Light Level 12
  • Weathered Copper Bulbs: Light Level 8
  • Oxidized Copper Bulbs: Light Level 4

Copper Grates

Copper Grates are a unique block because light can pass through them and mobs cannot spawn on them. They are unable to conduct Redstone but can become waterlogged like leaves. You'll need four Copper Blocks and a crafting table to make them. Place the first Copper Block in the center of the top row. Next, place the second and third blocks in the first and third blocks of the center row. Lastly, place the final Copper Block in the center of the bottom row.

Copper Doors

Unlike Iron Doors, Copper Doors can be opened by hand. This makes them more similar to wooden doors despite the fact that they are made from metal. To craft them, place one Copper Ingot in each box in the first and second columns of a crafting table. This recipe will produce three Copper Doors.

Copper Trapdoors

Similarly to the Copper Doors, Copper Trapdoors are closer to their wooden counterparts because they can be opened by hand. To craft them, fill each box in the top two rows of a crafting table with a single Copper Ingot. This will create two Copper Trapdoors for you to use.
