Learn how to break obsidian in Minecraft using the correct tools and fastest methods. Discover how to mine obsidian, avoid common mistakes, and collect it safely in Survival Mode.
If you’ve ever stared at a glowing pool of lava underground and thought, “I need to turn that into obsidian,” you’re in the right place. Obsidian is one of the most important blocks in Minecraft — you need it to build a Nether Portal, craft an Enchanting Table, make an Ender Chest, and construct a Beacon. The problem is that it can feel tricky to get, especially if you’ve accidentally mined it with the wrong pickaxe and watched it disappear.
This guide covers everything — how to make obsidian, where to find it, how to mine it correctly, and the fastest methods to stock up — whether you’re in early survival or planning an obsidian farm.
Quick Answer: To mine obsidian in Minecraft, pour water over a lava source block to create obsidian, then mine it using a Diamond Pickaxe or Netherite Pickaxe. Iron, Stone, Gold, and Wooden Pickaxes cannot collect obsidian — the block will break but drop nothing.
Obsidian Fast Facts:
- Requires Diamond or Netherite Pickaxe
- Cannot be crafted
- Forms when water touches a lava source block
- Used for Nether Portals, Ender Chests, and Enchanting Tables
- One of the strongest blocks in Minecraft
Fastest Way to Get Obsidian: Find a lava pool, pour water over the lava source blocks, and mine the resulting obsidian with a Netherite Pickaxe enchanted with Efficiency V.

What Do You Need to Mine Obsidian?
Best Tools for Mining Obsidian
Not every pickaxe can collect obsidian. Here’s the complete breakdown:
| Tool | Can Mine Obsidian? |
| Wooden Pickaxe | ❌ No |
| Stone Pickaxe | ❌ No |
| Iron Pickaxe | ❌ No |
| Gold Pickaxe | ❌ No |
| Diamond Pickaxe | ✅ Yes |
| Netherite Pickaxe | ✅ Yes |
Can You Mine Obsidian With an Iron Pickaxe?
No. This trips up a lot of players early on. You can swing an Iron Pickaxe at obsidian and it will go through the breaking animation — but when the block finally breaks, nothing drops. The obsidian is just gone. You waste time, tool durability, and the block itself.
The same applies to Stone, Gold, and Wooden pickaxes. Only Diamond or Netherite will actually give you the obsidian block.
How to Mine Obsidian Without a Diamond Pickaxe
If you don’t have a Diamond Pickaxe yet, mining isn’t an option. But you can still get obsidian through other routes:
- Ruined Portals contain pre-existing obsidian blocks that can be mined once you obtain a Diamond or Netherite Pickaxe.
- Loot Chests — Village Weaponsmith chests (3–7 obsidian), Bastion Remnant chests (4–6 obsidian), Nether Fortress chests, and Ruined Portal chests
- Piglin Bartering — toss a Gold Ingot to a Piglin for roughly an 8.71% chance of receiving obsidian
How to Mine Obsidian in Minecraft (Step-by-Step)
Here’s the full mining process from start to finish:
Step 1: Find or Create Obsidian
Either locate a natural obsidian formation underground or create it by pouring water over lava source blocks.
Step 2: Place Water Around the Area
Before you start mining, place your water bucket near the edge of the obsidian. Most lava pools have additional lava underneath the first obsidian layer, and the water will protect you and keep any freshly mined blocks from burning.
Step 3: Equip a Diamond or Netherite Pickaxe
Double-check your tool before swinging. Using anything else is wasted effort.
Step 4: Mine the Obsidian Block
Hold down your mining button. A Diamond Pickaxe takes about 9.4 seconds per block. A Netherite Pickaxe cuts that to around 8.35 seconds. Be patient — obsidian takes longer than almost any other block in the game.
Step 5: Collect the Obsidian
Pick it up before it can fall into any lava nearby. Moving your water source right beside where you’re mining keeps the area safe and pushes new obsidian drops away from any lava underneath.
Pro Tip: Keep water nearby because lava often sits underneath the first layer of obsidian. Mine at the edge where the water is flowing so any exposed lava gets converted before it can burn your drops.
How to Make Obsidian in Minecraft 1.21
Here’s the step-by-step process to intentionally create obsidian wherever you want it:
- Find a Lava Source Block — Look underground, in caves, or bring lava back in buckets.
- Craft a Water Bucket — Place 3 Iron Ingots (if you need help gathering iron, check out our Minecraft Iron Farm guide) in a V-shape at a Crafting Table, then fill the bucket at any water source.
- Pour Water Over the Lava — Pour your water one block above or beside the lava source. It will flow down and convert the lava source blocks into obsidian.
- Wait for the Conversion — It happens instantly once the water touches the source blocks.
- Mine the Obsidian — Use your Diamond or Netherite Pickaxe to collect it.
Note: Water cannot be placed in the Nether — it evaporates immediately. All obsidian creation with water must happen in the Overworld.
How to Find Obsidian in Minecraft
Find Obsidian Near Lava Pools
The most common source of obsidian is underground near natural lava pools, especially at lower Y-levels. When underground springs or water sources meet lava pools naturally, obsidian forms on its own. Keep an eye out when caving — you may spot dark purple blocks already formed along the edges of lava lakes.
Mine Ruined Portals
Ruined Portals generate across the Overworld and the Nether and are one of the best early-game obsidian sources. They always contain some obsidian blocks as part of their broken portal frame, and their loot chest has a 46.4% chance of holding 1–2 extra obsidian. If you find a Ruined Portal early in your game, consider repairing it rather than just mining it — you’ll need fewer blocks to complete the portal.
Pro Tip: Ruined Portals are often the easiest early-game obsidian source because the blocks are already formed. You just need your Diamond Pickaxe ready.
Search Woodland Mansions
Woodland Mansions have a secret room on the second or third floor containing 19 obsidian blocks and a diamond block hidden underneath. It’s a massive find, but Woodland Mansions are rare and dangerous to explore without solid gear.
Find Obsidian in The End
When you travel through an End Portal, a platform of 25 obsidian blocks spawns for you to land on. You can mine all of it, and it regenerates every time someone enters The End. The End also has tall obsidian pillars throughout the main island — these regenerate every time you respawn the Ender Dragon, making them a renewable obsidian source.
Get Obsidian Through Piglin Bartering
In the Nether, you can toss Gold Ingots at Piglins and hope for obsidian in return. The chance is approximately 8.71% per trade. It’s not the most reliable method, but if you’re already in the Nether with gold to spare, it’s worth doing on the side.
What Is Obsidian in Minecraft?
Obsidian is a deep purple-black block known for being one of the toughest materials in the game. It has a blast resistance of 1,200, which is the highest of any block you can obtain in Survival mode. That means creeper explosions, TNT, and even ghast fireballs can’t touch it.
One thing worth knowing: the Ender Dragon cannot destroy obsidian either. It can fly through obsidian pillars, but it won’t break them. The only mob that can break obsidian is the Wither, specifically through its blue wither skull attacks, which bypass blast resistance entirely.
What Is Obsidian Used For?
Obsidian is used for some of the most important things in Minecraft progression:
- Nether Portal guide — the gateway to the Nether dimension (minimum 10 blocks, full frame needs 14)
- Enchanting Table guide — you need 4 obsidian to craft one
- Ender Chest guide — requires 8 obsidian and 1 Eye of Ender
- Minecraft Beacon guide — obsidian forms part of the crafting recipe
- Blast-resistant structures — perfect for protecting bases on multiplayer servers
Can You Get Obsidian in Minecraft?
Yes, and there are several ways to do it. You can mine it from natural lava pools, loot it from chests, get it through Piglin bartering, mine Ruined Portals, or collect it in The End. You cannot, however, craft obsidian at a crafting table — it has no recipe. You always have to generate or find it.
How Do Obsidian Blocks Form in Minecraft?
Water + Lava Source Block = Obsidian
Obsidian forms when flowing water touches a lava source block. When that contact happens, the lava source converts into a solid obsidian block instantly. That’s it — that’s the whole recipe. No crafting table, no furnace, just water meeting still lava.
The key word here is “source block.” A lava source block is lava that’s sitting still, not moving or dripping. If you’re unsure whether lava is a source block, try picking it up with a bucket — if it fills the bucket, it’s a source block.
Why Am I Getting Cobblestone Instead of Obsidian?
This is one of the most common frustrations, and it comes down to one simple rule:
Water + Lava Source Block = Obsidian ✅
Water + Flowing Lava = Cobblestone ❌
If your lava is flowing (moving in a direction), pouring water on it will create cobblestone or stone, not obsidian. You need to target the still, stationary lava source blocks.
Tip: If you keep getting cobblestone, look further back toward where the lava is coming from. The source block is usually at the origin point of the flow, not at the edges.
How to Mine Obsidian in Minecraft Bedrock Edition
Does Bedrock Use the Same Method?
Yes — the core method is identical in Bedrock Edition. You still need a Diamond or Netherite Pickaxe, and you still create obsidian by pouring water onto lava source blocks.
Bedrock-Specific Tips
On Bedrock, the mining time for obsidian is slightly different — approximately 9.6 seconds with a standard Diamond Pickaxe, compared to 9.4 seconds on Java. The difference is minimal in practice.
Enchanting with Efficiency and using a Haste Beacon work the same way on Bedrock. Piglin bartering is available on Bedrock and is actually the most reliable automatic obsidian farming method for Bedrock players, since the Java-only Wither-based farms don’t apply.
Common Bedrock Mistakes
- Trying to place water in the Nether (it evaporates instantly on all editions)
- Using an Iron Pickaxe after misremembering the tool requirement
- Mining obsidian too close to a lava pool without a water buffer nearby
How to Mine Obsidian in Minecraft Java Edition
Java Edition Mining Method
The method is the same as the general guide above. A standard Diamond Pickaxe takes 9.4 seconds per block on Java, and a Netherite Pickaxe takes 8.35 seconds.
Java-Specific Obsidian Farm Options
Java Edition has more options for automated obsidian farming. Java Edition supports advanced portal-based and Wither-powered obsidian farms for late-game players who need large amounts of obsidian.
Fastest Way to Mine Obsidian in Minecraft
Quick Answer: The fastest way to mine obsidian is with a Netherite Pickaxe enchanted with Efficiency V under a Haste II Beacon effect. With this combination, each obsidian block takes just 1.55 seconds to mine.
Use a Netherite Pickaxe
A Netherite Pickaxe is slightly faster than Diamond at every enchantment level. On its own it mines obsidian in 8.35 seconds versus the Diamond Pickaxe’s 9.4 seconds — not a massive difference, but it adds up over a large farm.
Add Efficiency V
Efficiency is the most impactful enchantment for obsidian mining. Here’s how it stacks up on a Netherite Pickaxe without any Haste effect:
| Enchantment | Mining Time Per Block |
| None | 8.35 seconds |
| Efficiency I | 6.85 seconds |
| Efficiency II | 5.4 seconds |
| Efficiency III | 3.95 seconds |
| Efficiency IV | 2.9 seconds |
| Efficiency V | 2.15 seconds |
Use a Haste II Beacon
A Beacon with Haste II applied cuts your mining times even further. Combining Netherite Pickaxe + Efficiency V + Haste II brings each obsidian block down to 1.55 seconds — roughly six times faster than an unenchanted Diamond Pickaxe.
For reference, the same combo with a Diamond Pickaxe + Efficiency V + Haste II takes 1.6 seconds per block — nearly identical, so Netherite’s advantage is minimal at max enchantment.
Fastest Way to Get Obsidian in Minecraft
Best Ways to Get Obsidian
| Method | Difficulty | Renewable | Best For |
| Lava Pools | Easy | Yes | Beginners |
| Ruined Portals | Easy | No | Early Game |
| Piglin Bartering | Medium | Yes | Passive Collection |
| End Platform | Hard | Yes | Late Game |
| Portal Farming | Medium | Yes | Bulk Obsidian |
If mining is too slow right now, here are the fastest methods ranked by accessibility:
Method 1: Mine Natural Lava Pools
Find a lava lake underground, pour water, and mine. This is the classic method and available to anyone with a Diamond Pickaxe and a water bucket. Best for early-to-mid game.
Method 2: Loot Ruined Portals
Ruined Portals often have enough obsidian in their frame to get you started on a Nether Portal without any mining. Check the attached chest too — there’s a 46.4% chance of bonus obsidian inside.
Method 3: Piglin Bartering
Once you’re in the Nether, collect Gold and trade with Piglins. At roughly an 8.71% chance per gold ingot, you’ll accumulate obsidian passively while doing other Nether tasks. In Bedrock Edition, this is the best option for automated farming.
Method 4: End Platform Farming
Every time any entity enters The End, the 25-block obsidian platform regenerates. Travel in and out through the End Portal repeatedly to collect the platform each time. This is renewable and doesn’t require any lava setup.
Method 5: Nether Portal Farming
Build a second Nether Portal at least 16 blocks away from your first one in the Nether. Walk through it to generate a new portal in the Overworld — which contains 14 free obsidian blocks. Mine it, repeat the process. Each cycle gives you a fresh 14-block portal to strip.
Best Obsidian Method by Progression
- Early Game: Lava Pool + Water Bucket
- Mid Game: Ruined Portals
- Nether Stage: Piglin Bartering
- Late Game: Portal Farming
- End Game: Dripstone Lava Farm + Efficiency V
How to Get Obsidian Easily in Survival Mode
Best Early-Game Method
Your first goal should be getting 10 obsidian for a Nether Portal. The fastest route: find any lava pool, bring a water bucket and a Diamond Pickaxe, pour the water, and mine the obsidian. If you spot a Ruined Portal on your way, check whether it already has enough blocks to repair instead — that saves time.
Common Mistake: Many players rush to get a Diamond Pickaxe and then forget the water bucket. Always bring water when heading to a lava pool — it protects you and prevents your obsidian drops from burning.
Best Mid-Game Method
Once you have a Nether Portal, you can start portal farming. Build a second portal in the Nether at least 16 blocks from your first, walk through it back to the Overworld, mine the newly generated portal, and repeat. Each run nets 14 obsidian without needing to find new lava each time.
Best Late-Game Method
Build a dripstone lava farm to generate renewable lava, then pour and mine at scale. Pair it with a Netherite Pickaxe enchanted with Efficiency V and a Haste II Beacon for maximum speed. If you’re on Java Edition, a Piglin bartering farm linked to a gold farm can fill a double chest of obsidian overnight while you AFK.
How to Make an Obsidian Generator in Minecraft
Dripstone Lava Farm Setup
You can create a renewable lava source using pointed dripstone and a cauldron. Here’s how to build one:
- Place a Cauldron on the ground in a convenient spot.
- Place a Dripstone Block at least 2 blocks above the cauldron (no more than 7 blocks above).
- Attach a Pointed Dripstone to the underside of the dripstone block, pointing downward toward the cauldron.
- Place a Lava Source Block on top of the dripstone block.
- Wait about 20 minutes for lava to drip down and fill the cauldron.
- Collect the lava from the full cauldron using a bucket, then place it somewhere and pour water on it to create obsidian.
Is Obsidian Renewable?
Yes — through several methods. Nether Portals generate new obsidian frames each time they’re created. The End Platform regenerates on every entry. And with a dripstone lava farm, you can produce lava indefinitely and convert it to obsidian, making obsidian technically renewable in survival mode.
Why Can’t I Mine Obsidian?
Using the Wrong Pickaxe
This is the most common reason. If you’re using anything below Diamond, the block will break but drop nothing. Check your pickaxe before you start — it saves a lot of frustration.
Mining Too Early
If you start mining obsidian before placing water nearby, you risk uncovering lava underneath the block. That lava can destroy the dropped obsidian before you can pick it up. Always place water first.
Lava Destroying the Block
When you mine an obsidian block, the dropped item can fall into adjacent lava and burn. The fix is to stand in or next to your water source while mining — the water flowing over the area will protect dropped items and convert any newly exposed lava into more obsidian.
Not Holding the Mining Button Long Enough
Obsidian takes a long time to mine — 9.4 seconds with a Diamond Pickaxe unenchanted. If you release the button too early, the block resets its progress. Hold down consistently until the block fully breaks.
Fast Fact: Even with the best possible setup — Netherite Pickaxe + Efficiency V + Haste II — obsidian takes 1.55 seconds per block. Without any enchantments, a Diamond Pickaxe takes 9.4 seconds. There’s no shortcut around the mining time except better gear.
How to Get Obsidian Without Lava
If you’d rather skip the lava entirely, these sources all work:
- Ruined Portals — Found in the Overworld and the Nether. You can mine the obsidian frame blocks directly and check the loot chest for bonus obsidian.
- Piglin Bartering — Trade Gold Ingots with Piglins in the Nether for an approximately 8.71% chance of receiving obsidian per ingot.
- Village Weaponsmith Chests — Village weaponsmith chests have a 25.4% chance of containing 3–7 obsidian. Worth checking whenever you pass through a village.
- Bastion Remnants — Bastion generic chests have a 24.4% chance of containing 4–6 obsidian. If you’re exploring the Nether, Bastions are a solid obsidian source.
- End Structures — The End platform gives 25 obsidian per entry, and End Ships in End Cities contain additional obsidian blocks.
How Many Obsidian Blocks Do You Need for a Nether Portal?
Minimum Requirement — 10 Obsidian
The smallest possible Nether Portal frame is 4 blocks wide and 5 blocks tall. With corners not required, the minimum is 10 obsidian blocks. This gives you a functional portal, just barely.
Full Frame Requirement — 14 Obsidian
If you want to include all four corners, a standard portal uses 14 obsidian. Game-generated portals always include the corners, so when you mine a naturally spawned portal, you get 14 blocks.
How to Make a Nether Portal
- Arrange your obsidian in a vertical rectangle — 4 wide and 5 tall (with corners optional).
- Make sure the interior opening is at least 2 blocks wide and 3 blocks tall.
- Activate it by placing fire inside the frame using Flint and Steel or a Fire Charge.
- Walk through the purple portal to enter the Nether.
Tip: If you don’t want to mine obsidian at all for your first portal, find a Ruined Portal and repair it. You’ll need far fewer blocks since most of the frame is already there.
Frequently Asked Questions
What is the easiest way to mine obsidian in Minecraft?
Find a lava pool underground, pour a water bucket onto it to create obsidian, then mine with a Diamond or Netherite Pickaxe. Keep water flowing nearby to protect yourself and your drops from the lava underneath.
Do I put water on lava to make obsidian?
Yes — pour water onto a lava source block (not flowing lava) and it converts to obsidian instantly. Flowing lava gives you cobblestone, not obsidian.
Can you mine obsidian with an iron pickaxe?
No. The block will break after a long time, but it won’t drop anything. You need a Diamond or Netherite Pickaxe to actually collect obsidian.
Why can’t I mine obsidian?
You’re likely using the wrong pickaxe. Only Diamond or Netherite pickaxes collect obsidian. Anything else wastes the block entirely.
Is 10 obsidian enough for a Nether Portal?
Yes — a minimal 4×5 frame without corners needs only 10 obsidian. A full frame with all four corners requires 14.
Why am I only getting cobblestone instead of obsidian?
You’re pouring water on flowing lava rather than a lava source block. Target the still, stationary lava at the center or origin of the pool.
Can you craft obsidian in Minecraft?
No. Obsidian has no crafting recipe. You have to create it by combining water and lava, mine it from natural structures, or find it in loot chests.
Can you mine obsidian with gold?
No. Gold Pickaxes have extremely low durability and can’t collect obsidian regardless. Only Diamond and Netherite work.
Can TNT break obsidian?
No. Obsidian has a blast resistance of 1,200 — TNT explosions have nowhere near the power needed to break it. The Wither’s blue skull attack is the only standard in-game way to break obsidian besides a Diamond or Netherite Pickaxe.
Can the Ender Dragon destroy obsidian?
No. The Ender Dragon can fly through obsidian pillars without breaking them, which is why the End spikes stay intact throughout the fight.
Conclusion
Getting obsidian doesn’t have to be a headache once you understand the basics. Pour water over a lava source block, equip your Diamond or Netherite Pickaxe, and mine away — that’s the core loop. Always keep your water bucket nearby to protect yourself from lava underneath and to stop your drops from burning.
If you want obsidian fast, head to the nearest Ruined Portal to grab pre-existing blocks, or start portal farming once you’re in the Nether for a steady 14-block yield per run. For the absolute fastest mining speed, aim for a Netherite Pickaxe with Efficiency V and a Haste II Beacon — that combination gets you down to 1.55 seconds per block.
And if you’re serious about long-term supply, a dripstone lava farm gives you a renewable lava source you can keep converting to obsidian indefinitely. Set one up near your base and you’ll never have to hunt for lava pools again.
