Quick answer
- Put a lava source on top of a block, with
Pointed dripstone hanging under it. - Place a
Cauldron below the dripstone. - The cauldron fills with lava about every 19 minutes, forever.
Lava is the best furnace fuel in the game. One bucket smelts 100 items. With dripstone, you never run out.

How to build it
- Place a solid block, then put a lava source on top of it. Wall it in with non-flammable blocks.
- Hang pointed dripstone from the bottom of that block.
- Put a cauldron under the dripstone. The gap can be up to 10 blocks, with nothing in between.
Fire safetyKeep wood and wool well away from the lava. Use stone or cobblestone around it.
How fast it fills
~19 minaverage per cauldron
100items smelted per lava bucket
To get more lava, build more of them side by side. Then collect the lava from each cauldron with an empty bucket.
Using it
Use the lava in furnaces for huge batches. You keep the bucket after it burns, so just refill it from the cauldron.
Build a rowTen of these side by side give you roughly one bucket every 2 minutes on average.
