Cut Copper Slab is a cut copper variant of a slab. Unlike other types of slabs, cut copper slabs can oxidize over time. They generate naturally in trial chambers. Cut copper slabs can be mined with a stone pickaxe or higher. If mined without a pickaxe, they drop nothing.
They can be crafted using cut copper or obtained through stonecutting. Non-waxed cut copper slabs oxidize over time, progressing through exposed, weathered, and fully oxidized states unless waxed with a honeycomb. Cut copper slabs function like other slabs in terms of placement and collision. They can also be placed under note blocks to produce a bass drum sound.
