For a long time, water has been renewable in Minecraft, with infinite water sources created by placing two water source blocks two blocks apart. Lava, on the other hand, had not been renewable. Players were forced to search for new lava source blocks every time they wanted to use them, often walking into the Nether to steal from its oceans of lava. However, ever since the stalactite stone was added, infinite lava generation has become a reality in Minecraft.
With just a lava fountain, a piece of stalactite, and a cauldron, players can produce infinite amounts of lava with relative ease. This is perfect for any player looking to create an elaborate lava build in their home base, or any player who needs a lot of fuel. Players can also increase their lava production if they are willing to spend more cauldrons and stalactites.
How to make a lava generator in minecraft
These lava generators work by using Dripstone’s lava dripping mechanic. In a nutshell, placing a stalactite stalactite under a block that has lava on top of it will make it look like it’s dripping little drops of lava. By placing a cauldron under this drip stone, the lava will pool in the cauldron over time and eventually fill up. When this happens, players can use an iron bucket to collect the lava from the cauldron.
A large number of stalactites can be obtained from stalactite caves, where massive stalactites and stalagmites can be found. Placing more stalactites under a hanging stalactite block will create a larger stalactite, though size does not affect the rate of lava generation. Cauldrons, on the other hand, can be crafted using seven iron ingots arranged in a U-shape, like a pair of inverted iron shims. They are a bit pricey, but when the reward is infinite lava, the cost is well worth it.
There are some rules that players must follow when doing this. For one thing, the stalactite can’t be more than ten blocks long, and similarly, the cauldron must be within ten blocks of the dripstone’s lowest point. There must be no interfering blocks between the stone and the cauldron, and the block on which the lava rests must not be flammable, for obvious reasons. In addition, the lava on the block have to be a lava fountain block. Stalactite stalactites under lava blocks that are not a source will still leak lava, but cannot fill cauldrons.
Every time a random tick occurs in the game, what happens on average every 68 seconds, there will be a 5.9% chance that the cauldron will fill up. This means that players can get incredibly lucky and get some lava almost instantly, while sometimes players can wait quite a while. On average, players can expect to receive a single new lava source every 19 minutes. This may seem slow, but with each new lava source created, players can easily expand their lava generator, as seen below.
By having some air blocks between the stone and the cauldrons, players can walk along the edges of the cauldrons to easily pick up the central lava fountains. Unless the player can walk on lava, they must be very careful not to accidentally fall into a cauldron in the process. Lava can also be collected under cauldrons if players feel more comfortable doing so.
By expanding to a larger lava generator like the one above, players can exponentially increase their lava output. The generated lava fountains can be used to add more lava to the top of the generator, until the lava farm is producing at a rate the player is satisfied with. If a generator reaches 19 cauldrons and source blocks, players can expect to receive a new source of lava every minute.
