Polished Tuff is a refined variant of tuff, used primarily as a decorative block. It is crafted by combining four tuff blocks or obtained through stonecutting. Naturally, it generates in trial chambers, primarily as ceiling blocks.
It has the same hardness as tuff and is used to craft tuff bricks, slabs, stairs, and walls. Stonecutters allow direct conversion of tuff into its derivatives. When placed under a note block, it produces a 'bass drum' sound.
