Lava Bucket

Lava buckets are obtained by using a bucket on a lava source block. They are primarily used for transporting and placing lava, making them useful for fuel, traps, and cobblestone or obsidian generation.

Lava buckets serve as a long-lasting furnace fuel, smelting 100 items per bucket, making them one of the most efficient fuel sources in Minecraft. They can also be used for nether portals, automated farms, and defensive mechanisms.
