Weathered Copper

Weathered Copper is the third oxidation stage of copper blocks, appearing greener as it continues to oxidize over time. Like other copper blocks, it can be waxed with a honeycomb to prevent further oxidation. Weathered copper can be mined with a stone pickaxe or better; otherwise, it drops nothing.

It has a hardness of 3 and can be reverted to its previous oxidation stage by scraping it with an axe or by being struck by lightning. Weathered copper is mainly used for decoration, crafting cut copper, and as a storage block for copper ingots.
