Bazalte

Bazalte is a block which has a similar texture to obsidian, but with orange colouring. It is found in Volcano Biomes, commonly. Its blast resistance to explosions and it's immunity to Fire and Lava makes it good for shelters. It takes you 5 seconds to mine it using an Iron Pickaxe or a Diamond Pickaxe. Other Pickaxes will take 20 seconds and using bare hands or any non-pickaxe tools takes 55 seconds, it is also dropped from Lava Orges and Magma Cubes.

Spawn Blocking
Bazalte is very usaeful to stop spawning mobs, and will act like Lava towards undead mobs. If you set it ablaze using Flint and Steel once, the light level becomes 14 (15 if twice).

Harvesting
Bazalte, when harvested in its block form, drops 3-7 Bazalte Ashes, which are used for crafting items. If broken with a Silk Touch pickaxe, it drops itself as a block.
