Obsidian is the tough, dark block you need for a Nether portal, an enchanting table, an ender chest, and a beacon base. You do not craft it in a grid, though. You make it by pouring water onto lava, and then you have to mine it with the right pickaxe or you get nothing.
This guide covers exactly how obsidian forms, the pickaxe you need to mine it, the safe way to gather it, and a trick for building a Nether portal without a diamond pickaxe at all. Everything here is accurate for the latest 2026 version of Minecraft.
Quick answer: make obsidian by pouring water onto a lava source block. The lava turns to obsidian, which you then mine with a diamond or netherite pickaxe. Any weaker pickaxe destroys the block and drops nothing.

How to Make Obsidian
Obsidian forms when water touches a lava source block in the Overworld. This is the key detail: it must be a source block, not flowing lava. Flowing lava plus water makes cobblestone or stone instead.
The fastest way to get some:
- Find a lava pool (common in caves and ravines, or below Y0 near bedrock).
- Pour a bucket of water over the lava so it flows across the source blocks.
- Each source block turns into obsidian.
- Mine it with a diamond or netherite pickaxe.
You can also place lava from a bucket where you want it and then cover it with water to make obsidian exactly where you need it.
The Pickaxe Rule (Do Not Skip This)
This is the mistake that costs people their obsidian. Obsidian can only be collected with a diamond or netherite pickaxe. If you swing at it with iron, stone, or wood, the block still breaks eventually, but it drops nothing and your time is wasted.
Obsidian is also slow to mine even with the right tool, taking several seconds per block. Efficiency enchantments and a Haste beacon speed it up a lot if you are gathering a large amount.
The Safe Way to Mine It
Obsidian sits right next to lava, so mining it carelessly means falling into the lava it just replaced. Two ways to stay safe:
- Stand in water. Place a water source next to the obsidian and mine from inside the water. When the block breaks, the water flows in and cools any exposed lava before it can burn you.
- Wall it off. Bring blocks to seal off nearby lava so nothing spills while you dig.
No Diamond Pickaxe? Cast a Portal Instead
Here is the trick most players miss. You do not actually need a diamond pickaxe to build a Nether portal. Instead of mining obsidian and carrying it, you can cast the portal in place: place lava buckets in the portal frame shape, then pour water over the lava to convert it directly into obsidian right where it stands. The obsidian becomes the portal frame without ever being mined. This lets you reach the Nether before you have diamonds. A standard Nether portal needs a minimum of 10 obsidian (the four corners are optional, so a full frame is 14).
Where to Find Obsidian
You do not always have to make it. Obsidian generates naturally in several places:
- Where water meets lava in caves, the most common natural source.
- Ruined portals, found in both the Overworld and the Nether, are built partly from obsidian.
- The End has the most by far: the central obsidian pillars and end ships are full of it.
- Structures and chest loot like bastion remnants, woodland mansions, and village weaponsmiths.
- Piglin bartering. Trading gold to piglins in the Nether can occasionally return obsidian.
One thing that trips players up: crying obsidian is not the same block. It is used to make a respawn anchor and cannot be used for a Nether portal or an enchanting table, so do not mix them up.
What Obsidian Is Used For
Obsidian is one of the most important mid-game blocks:
- Nether portal: 10 to 14 obsidian to build the frame and travel to the Nether.
- Enchanting table: 4 obsidian, plus 2 diamonds and 1 book. This is your gateway to enchanting.
- Ender chest: 8 obsidian and 1 eye of ender, for a shared storage that follows you everywhere.
- Beacon base: obsidian counts toward the pyramid you build under a beacon.
- Blast-resistant builds: obsidian shrugs off creeper, TNT, and even Ender Dragon damage (only the Wither’s blue skulls can break it), so it is popular for secure walls and PvP bases.
