Weathered Chiseled Copper is a decorative copper block that has undergone further oxidation, giving it a greener, more corroded appearance. It naturally generates in trial chambers and can also be crafted from 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 requires a moderate amount of time to break. Like other copper blocks, it will continue oxidizing unless waxed with a honeycomb. It can also be scraped with an axe to revert to Exposed Chiseled Copper or struck by lightning to reset oxidation entirely.
