Andesite Slab is an andesite variant of a slab. It does not generate naturally and must be crafted or obtained through stonecutting. Andesite slabs can be mined with any pickaxe. If mined without a pickaxe, they drop nothing.
They can be crafted using andesite or obtained through stonecutting. Andesite 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.
