Learn how to create an obsidian generator in Minecraft that maximizes efficiency and saves time. This article provides a step-by-step tutorial, safety precautions, tips and tricks, and a comparison of different designs.


If you have played Minecraft, you know how important obsidian is for creating portals and other essential items. However, creating obsidian can be a long and tedious process, especially if you need a lot of it. That’s where an obsidian generator comes in. In this article, we will show you how to build an obsidian generator from scratch. This guide will help you maximize your efficiency and save time so you can focus on playing the game.

Step-by-step Tutorial

To build an obsidian generator, you will need the following materials:

  • One bucket of water
  • One bucket of lava
  • Building blocks (cobblestone, stone, or any other non-flammable block)
  • Pickaxe (at least iron level)

Follow these steps to construct the generator:

  1. Build a three-block wide and one-block deep hole in the ground.
  2. Place the water in one of the corners of the hole.
  3. Place the lava in the opposite corner of the hole.
  4. The lava and water will meet and create obsidian.
  5. Use your pickaxe to mine the obsidian blocks.

It’s important to note that the obsidian will only generated along the border between the water and lava source blocks. Therefore, to maximize efficiency, it’s recommended to build your generator so that the lava and water are as close as possible.

Case Study

Jane was a Minecraft player who wanted to create a portal to the Nether. However, she quickly realized how hard it was to gather the necessary 10 obsidian blocks. That’s when she decided to build an obsidian generator. It took her less than 30 minutes to construct the generator and obtain the required blocks. This helped her achieve her goal and allowed her to explore the new world of the Nether.

Tips and Tricks

Here are some tips and tricks that will help you build an efficient and cost-effective obsidian generator:

  • Always have a bucket of water with you. This will help you avoid falling into lava or getting burned while mining the obsidian.
  • Build your generator near your base. This will save you time and effort when you need to create obsidian.
  • Use a fire resistance potion to prevent damage when standing in the lava while mining the obsidian blocks.
  • Don’t stand too close to the lava, or it could push you into the fire or lava. Maintain a safe distance.
  • Use a diamond pickaxe for faster obsidian mining.

Mistakes to Avoid

Here are some common mistakes that players make when building an obsidian generator:

  • Not placing the water and lava sources in the correct corners which will result in no obsidian generation.
  • Building the generator too far from the base, making it difficult to collect the obsidian.
  • Standing too close to the lava, resulting in damage or death.
  • Not having the right materials or pickaxe to mine the obsidian.
  • Building the generator in a flammable area such as a forest or wooden structure, potentially leading to catastrophic fires.

Be sure to avoid these mistakes to ensure that your obsidian generator works efficiently and safely.

Safety Precautions

It’s important to remember that playing Minecraft can potentially cause harm if not done properly. Here are some safety precautions you should follow:

  • Always have a bucket of water to prevent damage and injury from lava.
  • Avoid standing too close to lava or fire, especially when mining obsidian blocks.
  • Wear appropriate gear, such as fire resistance potions, to prevent damage and injury.
  • Build your generator in a safe area, away from other flammable structures or environments.

Comparing Different Designs

There are different designs and variations of obsidian generators. Some are more efficient and cost-effective than others. Here are some of the main designs:

  • Single-block generator – the simplest design that requires only one lava source block. Its efficiency is limited and results in fewer obsidian blocks.
  • Double-block generator – the most common design, twice as efficient as the single-block generator and requires two lava source blocks.
  • Nether portal generator – the most effective and efficient design. Creates obsidian as a byproduct of creating a Nether portal. This method requires building the portal frame with the water in place, then removing the frame leaving the obsidian.

Choose the design that is most suitable for your skill level, goal, and intended gameplay mode.


Building an obsidian generator in Minecraft is a relatively simple process that can save a lot of time and effort. It’s important to follow the instructions carefully, take safety precautions, and be mindful of mistakes that could ruin the process. With these tips, you can create an efficient and cost-effective generator that will help you achieve your goals and maximize your gameplay.
