Oxidised Chiselled Copper

The Oxidised Chiselled 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 and can also be crafted using 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.
