Oxidized Chiseled Copper is the final stage of oxidation for chiseled copper, featuring a fully greenish-blue patina. It is a decorative block that naturally generates in trial chambers in its waxed form and can also be crafted using oxidized cut copper slabs or obtained through stonecutting.
It can be mined with a stone pickaxe or better; otherwise, it drops nothing. With a hardness of 3, it takes a moderate amount of time to break. Unlike previous oxidation stages, it cannot oxidize further but can be waxed with a honeycomb to prevent changes or scraped with an axe to revert to Weathered Chiseled Copper. A lightning strike will fully remove oxidation, restoring it to its original state.
