The Minecraft Caves & Cliffs update is coming in the summer of 2021, and with it comes a plethora of new mobs, land formations, and a brand-new ore: copper. While we got a new type of ore in the Nether Update, it’s been a while since a new ore type has been introduced into the overworld, the most recent being emerald. Caves & Cliffs will also be the first update to add an ore that changes in appearance over time.
It’s important to note that copper is the same rarity as iron, rather than a rarer tier ore like gold or diamond, so it will not be super difficult to find. Like Iron, Copper only needs a stone pickaxe or better in order to mine it. You can only find mineral veins of Copper Ore in the Overworld. The ore will not be present in The End or the Nether, and not even in an altered form like Gold.
Copper can be found in the Overworld from level 4 to level 63, and like iron and gold, it must be smelted in order to acquire its ingots.
Copper Ingots can be crafted into blocks, slabs, and stairs, or cut into Cut Copper making it perfect for decorating — but if you want that shiny bronze look forever, you are going to need to wax it. Otherwise, once Copper Blocks are crafted into any shape and are placed, they will naturally oxidize over time like real copper.
Oxidation will not change any play mechanic or interactive element — the changes over time are purely cosmetic. In terms on non-decorative uses, copper can also be used to craft a lightning rod or a spyglass.
The image above details what a building may look like in the middle of the oxidation process. Once enough time has passed, the block will turn entirely into that shade of green, but this process will take several day-night cycles, so don’t expect it to happen overnight.
Design-wise, this would be perfect for rebuilds of something like the Statue of Liberty, perhaps the most iconic oxidized landmark. Or, you can create your own design, and maybe in due time, it too will be iconic.
