Blackstone is a dark-colored block found exclusively in the Nether, primarily in basalt deltas and bastion remnants. It functions similarly to cobblestone and can be used to craft stone tools, brewing stands, and furnaces.
Blackstone can be obtained by mining it with a pickaxe or through Piglin bartering. It can also be crafted into polished blackstone, slabs, stairs, and walls. Placing it under a note block creates a 'bass drum' sound.
