The Waxed Oxidized Copper Bars is a decorative and semi-transparent block representing the preserved final oxidation stage of Copper Bars. It features a fully aged teal surface with deep green highlights, giving it a distinct patinated copper look that remains unchanged over time. As a waxed variant, the Waxed Oxidized Copper Bars does not oxidize further, permanently retaining its oxidized appearance.

The Waxed Oxidized Copper Bars is obtained by applying Honeycomb to Oxidized Copper Bars. It connects smoothly to other bars, solid blocks, and fences, making it perfect for detailed architecture, windows, and ornamental structures. The block is waterloggable, non-flammable, and can be mined with any pickaxe to drop itself. With a hardness of 5 and a blast resistance of 6, the Waxed Oxidized Copper Bars combines durability with a striking, weathered teal finish, ideal for builders who want a stable, fully patinated copper aesthetic.
