So, you’re tired of trekking across the Overworld just to fill a few buckets. I get it. For years, the Minecraft community was stuck with a harsh reality: water is infinite, but lava is a finite resource. You’d find a pool, drain it, and then you’d have to go deeper or venture into the Nether just to fuel your furnaces. It was a massive pain. But things changed with the 1.17 Caves & Cliffs update. Mojang finally gave us a way to "grow" lava, though it’s not exactly the same as clicking two water buckets into a hole.
If you’re looking to make an infinite lava source, you need to stop thinking about 2x2 pools. That doesn't work here. If you try to place two lava sources next to each other, they just sit there. They don't create a third source block. Instead, we have to use mechanics involving Pointed Dripstone and Cauldrons. It’s a bit of a slow burn, literally, but once you set it up, you’ll never need to visit a lava lake again.
Why the Old 2x2 Trick Fails Every Time
Minecraft physics are weird. Water behaves like a fluid that wants to multiply. Lava, however, behaves more like a thick, stubborn sludge. In the game's code, a water source block is created if a vacant space is flavored by two adjacent source blocks. Lava doesn't have this property in the standard game.

You’ve probably seen some old "glitch" videos claiming you can make a 3x1 lava infinite source. Honestly? Those are either outdated mods or flat-out fakes. In vanilla Minecraft, whether you are on Bedrock or Java Edition, the only legitimate way to generate a renewable supply of lava is through the dripstone method. It's essentially a renewable resource farm rather than a "source" in the traditional sense.
Setting Up Your Dripstone Lava Farm
To get started, you need three specific items: a Cauldron, a piece of Pointed Dripstone, and a bucket of lava to start the process. You’ll also need a non-flammable block—think cobblestone, deepslate, or glass. Do not use wood. I've seen too many people burn their entire base down because they thought a wooden ceiling would hold back molten rock.
First, place your Cauldron on the ground. This is your collection vessel. Leave two blocks of air above the Cauldron. On the third block up, place your solid, non-flammable block. Underneath that block, attach your Pointed Dripstone. It should look like a little spike hanging down, pointing directly into the Cauldron. Now, go to the top of that solid block and create a small "cup" or enclosure to hold your lava source block.
When you pour the lava into that top enclosure, the Pointed Dripstone will start to "bleed." You’ll see orange particles dripping from the tip of the stone. This is the magic happening. Over time—and it varies based on random ticks—the lava drips will slowly fill the Cauldron.
How Long Does It Actually Take?
It is slow. Really slow. On average, it takes about 15 to 20 minutes of real-world time for a single Cauldron to fill up. Sometimes you get lucky and it happens in five. Sometimes it feels like an eternity. Because the mechanic relies on the random tick speed of the game, there is no way to "speed it up" other than building more modules.
If you only have one Cauldron, you’re going to be disappointed. To actually make an infinite lava source that’s useful for a massive super-smelter or a decorative build, you need a line of at least 10 to 20 Cauldrons. Since Pointed Dripstone is easily farmable (you just need one and some water to grow more), expanding your farm is mostly just a matter of mining enough iron for the Cauldrons.
Troubleshooting the Drip
If your Cauldron isn't filling up, check your gaps. There must be exactly one block of Pointed Dripstone hanging. If the dripstone is touching the Cauldron, it won't work. If there's a block in the way, it won't work. Also, make sure the lava source is directly above the block holding the dripstone.
One thing people often forget: the lava must be a source block. A flowing stream of lava won't trigger the drip mechanic. You need to dump a fresh bucket right on top of the block holding the dripstone.
Java vs. Bedrock Differences
Surprisingly, this is one of the few features that works almost identically across both versions of the game. Whether you’re on a high-end PC or playing on your phone, the dripstone-to-cauldron ratio remains the same. The only real difference is how you might automate it. On Bedrock, you can actually move Cauldrons with Pistons. This opens up some wild possibilities for automated lava collection systems that cycle filled Cauldrons past a player, though Java players are still stuck manually clicking each one with a bucket.
Advanced Strategies: Mass Production
If you're at the endgame and need thousands of buckets for a project, you shouldn't just line these up in a row. Build a grid. A 10x10 grid of Cauldrons with a ceiling of lava will give you 100 buckets of lava every half hour or so.
- Materials needed: 100 Cauldrons, 100 Pointed Dripstone, 100 Lava Buckets.
- Safety tip: Enclose the lava in glass so you can see if any source blocks accidentally turn into obsidian (though this shouldn't happen if your enclosure is airtight).
- Efficiency: Use a "flying machine" or a simple walkway above the cauldrons so you can hold down the right-click button and fly by to collect the lava quickly.
I’ve seen players try to use this for fuel in a blast furnace. It’s incredibly efficient. A single bucket of lava smells 100 items. If you have a farm of 20 Cauldrons, you’re basically looking at 2,000 smelted items per cycle. That’s significantly better than chopping down trees for charcoal or mining coal ore every time you need to refine some iron or gold.
Common Misconceptions About Lava
A lot of players think that because they found a huge lava lake in a cave, they should just build their base there. Honestly, that's a recipe for a "You Died" screen. Moving your lava production to a controlled, dripstone-based environment is much safer.
Another big myth is that the thickness of the lava pool above the dripstone matters. It doesn’t. You only need a single layer of source blocks. Adding a second layer of lava on top won't make the dripstone drip any faster. The game only checks if there is a source block immediately above the block the dripstone is attached to. Save your extra lava buckets for filling more modules rather than stacking them vertically.
The Dripstone Growth Factor
If you're starting from scratch and can't find a Dripstone Cave, look for Wandering Traders. They often sell Pointed Dripstone for a few Emeralds. Once you have two pieces, you can place one on the ceiling and one on the floor with a gap between them. If water is above the top one, it will eventually grow and meet the bottom one, giving you infinite dripstone to expand your lava farm.
The Logistics of Fuel
Let’s talk about why you’re doing this. Usually, it’s for fuel. Lava is the best fuel in the game, but it has one major drawback: it leaves the empty bucket in the furnace's fuel slot. This can break some automated hopper systems if you aren't careful. If you’re building a massive industrial district, you’ll need a filter system to pull those empty buckets out and cycle them back to your lava farm.
It’s these little nuances that separate a casual player from someone who really understands the mechanics. Setting up the farm is easy. Integrating it into a working base is where the real challenge lies.
Practical Next Steps
Now that you know the mechanics, your first move should be heading to a Dripstone Cave or finding a Trader. Don’t bother trying the 2x2 hole; it's a waste of time.
Start by crafting five Cauldrons. Place them in a line with a one-block gap above them, followed by your non-flammable blocks and Pointed Dripstone. Fill the top with lava and just go about your business. Check back in twenty minutes. You’ll have five fresh buckets of lava waiting for you. From there, just keep doubling the size of the farm until you have more fuel than you know what to do with. If you're feeling ambitious, try building a vertical tower of these farms to save on floor space. Just remember to keep the lava contained, or you'll be spending your afternoon cleaning up a fire instead of smelting your ores.
