Smooth Quartz Slab is a smooth quartz variant of a slab. It generates naturally in bastion remnants. Smooth quartz slabs can be mined with any pickaxe. If mined without a pickaxe, they drop nothing.
They can be crafted using smooth quartz blocks or obtained through stonecutting. Smooth quartz 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.
