Copper is a unique fused block that you can place all over the house in Minecraft. Over time, this material changes from dark orange to green in a process known as oxidation. To stop this, you can apply a honeycomb slice to any of your copper blocks and turn it into a waxed block to prevent further oxidation, essentially freezing it in its current color. When you first place the copper block, how long do you have until oxidation? There are four color grades.
The process of copper undergoing oxidation is not increased or accelerated by exposure to weathering, so rain, water and air have no effect on it. Instead, it’s all about ticks in your Minecraft world. Ticks occur every 0.05 seconds, so there are 20 ticks every second in your game. A random tick occurs in the background, but you can expect the copper block to oxidize about every 20 minutes.
It doesn’t matter if you leave your blocks outside or accumulate them in your settlement, away from the natural elements of your Minecraft world. Eventually, they will go through an oxidation process if they are not waxed with a honeycomb. You can return an oxidized piece of copper to its original color by hitting it with an ax or striking it with lightning. If you use an ax, it must be a waxed version of copper.
