Waxed Oxidized Cut Copper Slab is a decorative metal slab crafted by applying honeycomb to an oxidized cut copper slab, preventing it from changing appearance. Unlike regular cut copper slabs, this variant retains its fully oxidized teal-green color permanently and does not revert when struck by lightning or scraped with an axe.

It can be obtained through crafting or stonecutting and is mineable with a stone pickaxe or better. Waxed oxidized cut copper slabs are commonly used in construction and decorative builds, providing a stable and weathered aesthetic without the risk of further transformation.
