Lava Bucket

A lava bucket is a bucket filled with lava, which is the only way to carry it as an item. It can be used as fuel, smelting 100 items.

To fill an empty bucket with lava, it needs to be used on a lava source block or lava in a cauldron. The block is consumed in the process. Flowing lava does not fill a bucket.

A lava bucket can be used to place down lava sources with the use item button. Doing so gives the player the bucket back. Lava buckets can be used to replace some transparent, non-full blocks such as short grass and water, both flowing and sources.
