Oxidized Copper Door is the fully oxidized copper door, with a distinct teal-green appearance. Like other copper doors, it can be opened and closed manually without requiring redstone. It generates naturally in trial chambers in its waxed form. Oxidized copper doors can be mined with any tool, but pickaxes are the fastest. Unlike iron doors, they can be opened by players, villagers, piglins, wandering traders, and vindicators.
Oxidized copper doors do not oxidize further but can have their oxidation removed using an axe or lightning. They can also be waxed with honeycomb to prevent oxidation from being removed. In Hard difficulty, zombies and vindicators can break oxidized copper doors, making them less secure. However, they can still be controlled with redstone power. Additionally, oxidized copper doors can be used as air pockets underwater and in lava since they do not burn.
