Waxed Oxidised Copper Door

Waxed Oxidised Copper Door is a copper door variant that has been treated with honeycomb to preserve its fully oxidized state. Like other copper doors, it can be opened and closed manually without requiring redstone. It is craftable by combining an oxidized copper door with honeycomb and does not change its appearance over time. Waxed Oxidised Copper Door 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.

Since it is waxed, Waxed Oxidised Copper Door retains its teal coloration indefinitely without reverting or oxidizing further. In Hard difficulty, zombies and vindicators can break Waxed Oxidised Copper Door, making them less secure. However, they can still be controlled with redstone power. Additionally, Waxed Oxidised Copper Door can be used as air pockets underwater and in lava since they do not burn.
