How To Make Infinite Lava Source

How To Make Infinite Lava Source in Minecraft 1.20

In the ever‑expanding world of Minecraft, having a reliable supply of lava is a game‑changer. Whether you’re building a lava moat, powering a furnace, or creating a lava‑based redstone contraption, an infinite source saves you from constantly mining or trading for this valuable fluid. This guide explains three proven methods that work in Minecraft 1.20, each with clear step‑by‑step instructions. You’ll learn the classic trick, a bucket‑free generator, and a fully automated system that can be used in survival or creative mode.

Why You Need Infinite Lava

Without an endless supply of lava, players often resort to mining obsidian or trading with villagers—both time‑consuming and resource‑heavy. An infinite source:

Reduces resource waste: No need to keep mining for new lava buckets.
Speeds up building: Instant lava placement for large projects.
Enables automation: Power furnaces, create lava‑powered piston mechanisms, or build lava farms.
Facilitates exploration: Carry lava for quick escapes or to create a safe path over lava pools.

With the methods below, you’ll never run out of lava again—unless you’re playing on a hardcore server that disables all crafting.

Method 1: The Classic 2‑Block Trick

The most straightforward way to produce an infinite lava source is the classic 2‑block trick. This method works in any version of Minecraft, including 1.20, and requires only a single source block of lava and a bucket of water.

Step‑by‑Step Guide

Place a lava source block in a flat area.
Position a water source block directly adjacent to the lava block.
When the water touches the lava, the two combine to form obsidian at the point of contact.
Remove the water block and replace it with another lava source block using a bucket or a lava‑filling method.
Repeat the process: each time you add lava to the water, obsidian forms, and the water block can be reused.

Because the lava source block remains in place, you can continuously replace the water to create a new lava source every few seconds. The trick is simple, but it does require a bucket or a way to collect the lava each time.
