Blackstone

Blackstone is a dark colored block, which functions similarly to cobblestone. It can be found only in the Nether.

Polished blackstone is the polished version of blackstone, which functions similarly to stone.

Chiseled polished blackstone is the chiseled version of polished blackstone.

Natural generation
Blackstone generates naturally in the basalt deltas biome found in the Nether. $$, Medium sized veins can also generate in all nether biomes, similarly to gravel.

From block loot
Blackstone requires a pickaxe to be mined, in which case it drops itself. When mined without a pickaxe, it drops nothing.

Usage
Blackstone can be used as a substitute for cobblestone in the Nether as it can be used to craft stone tools and furnaces. It can also be used to craft polished blackstone, which can be further crafted into blackstone bricks.

Trivia

 * Although it can be used to craft stone tools and furnaces, it cannot be used to craft dispensers, droppers, pistons or other blocks that use cobblestone in their recipes.
 * Similarly to chiseled sandstone, red sandstone, and netherbrick, chiseled polished blackstone has a face/symbol in its texture - in this case, a piglin snout.
