Basalt

Basalt is a type of igneous rock found in the Nether.

Polished basalt is the polished version of basalt.

Natural generation
Basalt generates naturally as basalt pillars, which are found in the biome. They also generate in biomes as regular terrain and as part of basalt column.

Breaking
Basalt drops as an item if mined by any pickaxe. If mined by any other tool, it drops nothing.

Post-generation
Basalt can also be made by lava flowing into a space that is on top of soul soil and next to blue ice. The lava is replaced with basalt.

Usage
Basalt is currently used only for decoration. Like blocks such as logs and quartz pillars, basalt can face either horizontally or vertically depending on how they are placed; they face in the direction of the surface they are placed on.

Basalt cannot be destroyed by Ghast fireballs.
