The Oxidised Cut Copper Slab is the final oxidized stage of a cut copper slab. It generates naturally in trial chambers. Oxidised Cut Copper Slab can be mined with a stone pickaxe or higher. If mined without a pickaxe, they drop nothing.
They can be crafted using oxidized cut copper or obtained through stonecutting. Unlike other cut copper slabs, Oxidised Cut Copper Slab no longer undergo further oxidation. However, their oxidation can be removed by striking them with lightning or using an axe. Oxidised Cut Copper Slab function like other slabs in terms of placement and collision. They can also be placed under note blocks to produce a bass drum sound.
