How to wax and remove wax from Copper to prevent or resume oxidizing in Minecraft

Halt the oxidation process to give your builds a timeless look.

Waxing Copper with Honeycomb

For the first time since emeralds, a new common-tier Overworld ore has joined the ranks. Copper is the newest metal in Minecraft. Copper will not be in the Latest Release of Minecraft until the Caves and Cliffs major update, but has been present in the Minecraft Snapshot since 20w45a. The thing that makes copper special is that once you craft and place a copper block down, it, like real copper, will slowly begin to oxidize.

Oxidation will turn the block from a shiny bronze color into an eventually solid teal over the course of four stages: Copper Block, Exposed Copper Block, Weathered Copper Block, and Oxidized Copper Block.

Waxing and removing wax from Copper

The first thing you should note is that all copper can be waxed until it is fully oxidized, including blocks, slabs, stairs, and even cut copper variants. This also means that you can wax Copper in its base form, or in its Exposed or Weathered forms too, to keep it like that forever.

The only major ingredient you will need to wax your copper is Honeycomb, and there are multiple ways to apply it, and as of Snapshot 21w11a, two ways to take it off.

Waxing Copper

The easiest way to wax copper in bulk is through a crafting recipe. Placing a Honeycomb and a Copper Block in a Crafting Square will create a Waxed Copper Block. The same goes for Exposed Copper Blocks and Weathered Copper Blocks.

The second way to wax Copper Blocks is to press Use Item on a placed Copper Block while Honeycomb is in your hand. This will wax the same three varieties of Copper as the crafting table method, but doesn’t require you to pick up Copper if you decide to wax it after you build with it.

The last way is to apply Honeycomb to Copper Blocks via a Dispenser. It will affect the Copper Blocks in the same way as the second method.

Removing Wax

If you have waxed copper but decide you don’t want it to be that way, there is no direct Crafting Square reverse method, but there is a two-step workaround so that you can take off the wax in bulk. To use a Crafting Square, place a Waxed Copper Block in the Crafting Square, and turn it back into 4 Copper Ingots. Then place those 4 ingots in a square to craft a Copper Block. It will not be waxed. This only works for Waxed Copper Blocks, not on the waxed Exposed or Weathered variants.

You can also scrape wax off of any type of waxed Copper one-by-one once it is already placed. Similar to taking the bark off of a tree log, you can Use Item with an axe of any tier in hand on a Waxed Copper Block to scrape the wax off of it. It will go back to its non-waxed state at whatever point in its oxidation it is at. While it is less efficient than the prior method, it is currently the only method to clean wax off of Exposed and Weathered Copper. It is luckily also more convenient than the prior method if you want an already-built creation to oxidize, as you don’t need to replace any blocks.

Note: There is no way to get your Honeycomb back from either of these methods.

Non-waxable Copper and Cleaning Oxidization

Oxidized Copper is the only form of Copper that cannot be waxed, as there is no oxidation left to prevent — it is already at the final stage. If you truly wish to wax a block that has been fully oxidized, the only way to do that is to clean the oxidization of the block first. A Copper Block can become unoxidized is if it is stricken with Lightning. This will reset any stage of oxidization, even if it is fully oxidized. If this does occur, you can wax the block once again, but lightning currently the only method of cleaning oxidization, makes doing so more trouble than it is worth.
