Unleash Your Inner SkyFactory Alchemist: Cobblestone & Crucible Power!
(how to connect cobblestone generator and crucible skyfactory 3)
Ever stared at your SkyFactory 3 island, dreaming of endless lava for your smeltery or power needs? You need the classic combo: the Cobblestone Generator feeding the Crucible. It’s a fundamental setup, but getting it just right unlocks so much potential. Let’s dive into how to link these workhorses seamlessly.
Main Product Keywords: Cobblestone Generator, Crucible
1. What is the Cobblestone Generator and Crucible Combo?
Think of this pair as your island’s basic engine for making lava. The Cobblestone Generator is a simple machine. It uses water and lava source blocks placed carefully. When water flows into lava, it creates cobblestone. When lava flows into water, it creates stone. But set up correctly, it endlessly produces cobblestone blocks where the two fluids meet. It’s reliable and cheap.
The Crucible is a tank. You put solid blocks into it, and if you heat it, it melts them into liquids. For making lava, you put cobblestone (or stone, or gravel) into the crucible. Then you apply heat. The heat source matters. It affects how fast the cobblestone melts into lava. Common heat sources include fire, lava itself placed underneath, or special heaters like the Heater from Ex Nihilo Creatio.
Linking them means the cobblestone made by the generator automatically goes into the crucible. The crucible then melts it down into lava. This lava can then be piped out for power, casting, or other uses. It’s a closed-loop system generating fuel from essentially nothing but water and a little initial lava.
2. Why Connect Them? The Power of Automation!
Doing things manually in SkyFactory 3 gets old fast. Imagine mining cobblestone by hand, then walking it over to your crucible, feeding it piece by piece, waiting for it to melt. It’s slow and eats up your time. Connecting the generator to the crucible automates this entire process.
Once set up, the system runs itself. Cobblestone is made automatically. It’s moved automatically to the crucible. The crucible melts it automatically. You get a steady stream of lava without lifting a finger. This lava is incredibly valuable. It fuels the Smeltery for alloying metals. It powers Magmatic Dynamos for generating RF energy. It’s used in casting basins for making obsidian or other blocks. Automation means you can focus on bigger projects, like expanding your power grid or exploring new mods, while your lava factory hums along. Efficiency is key to progress.
3. How to Connect Them: The Step-by-Step SkyFactory Way
Setting this up is straightforward. Follow these steps carefully:
Step 1: Build Your Cobblestone Generator. Find a flat spot. Place two blocks side-by-side with a one-block gap between them. Put a lava source block on one side block. Put a water source block on the opposite side block. Water and lava will flow towards each other in the gap. Where they meet, cobblestone will form constantly. You might need to mine the first few blocks to get the flow started correctly. Use a block breaker like the Block Placer (set to break mode) or a Mechanical User to automatically harvest the cobblestone as it appears. Point the output of this breaker towards your crucible setup direction.
Step 2: Place Your Crucible. Position the Crucible close to your generator’s output point. Put it directly adjacent or leave a small gap. Crucibles can be placed on the ground or potentially on a block. Ensure the top is clear for input.
Step 3: Add the Heat Source. This is crucial. Without heat, the crucible won’t melt anything. Place your heat source directly underneath the crucible. Early game, this is often a block of Netherrack set on fire using a flint and steel. You can also place a lava source block underneath. Later, upgrade to a Heater block powered by RF for much faster melting.
Step 4: Connect with Item Transfer. You need a way to move the cobblestone from the generator breaker into the crucible. The simplest method is using a Hopper. Place the hopper on top of the crucible. Make sure its output faces down into the crucible. Then, place another hopper pointing into the first hopper. Position the cobblestone generator breaker so it outputs directly into the top hopper. Cobblestone will fall from the breaker, go into the top hopper, transfer to the bottom hopper, and then into the crucible. You can also use Item Transfer Nodes or Conduits if you have them. Connect the output of your breaker to the input of your transfer system. Connect the output of the transfer system to the crucible.
Step 5: Fuel the Crucible (Netherrack Fire). If using Netherrack and fire, ensure the Netherrack is lit. The fire should be touching the bottom of the crucible. The crucible UI will show a flame icon when heated properly. For lava or heaters, just ensure they are placed correctly underneath.
Step 6: Collect Your Lava! As cobblestone enters the heated crucible, it will melt into lava. Use Fluid Transfer Nodes, Conduits, or Fluiducts to pipe the lava out. Connect the pipe to the crucible’s output side (usually marked or configurable). Route the lava to tanks, dynamos, or your smeltery drain. Congratulations! Your automated lava factory is live.
4. Applications: What Can You Do With All That Lava?
Endless lava opens many doors in SkyFactory 3. Here’s what you can power:
Smeltery Fuel: The Smeltery needs fuel to melt ores and alloys. Lava is a perfect fuel source. Pipe lava directly into the Seared Tank or drain. This keeps your metal production running non-stop.
Magmatic Dynamos: These generators convert lava directly into RF power. One crucible setup can often fuel several dynamos, creating a steady power source for your base. Scale up your generator and crucible count for more power.
Obsidian Production: Pouring lava onto water in a Casting Basin makes obsidian. Need obsidian for tools, platforms, or other recipes? Your lava factory provides the key ingredient effortlessly.
Other Crucible Uses: Crucibles can melt other materials. You can automate melting wood into charcoal for fuel, or other blocks for their fluids. The principle is the same – automate input and heat.
General Fluid Needs: Lava might be required for other mod recipes or processes. Having a reliable source means you’re always prepared.
5. FAQs: Solving Common SkyFactory Cobble-Crucible Hiccups
Here are answers to frequent questions:
Why isn’t my crucible melting cobblestone? Check the heat source! Is the fire lit under Netherrack? Is the lava source block directly underneath? Is the Heater powered? Ensure the crucible UI shows the heating flame icon. Also, ensure cobblestone is actually entering the crucible – check hopper connections.
My cobblestone is piling up, not going into the crucible. Why? Your transfer system might be clogged or misdirected. Double-check hopper directions – they only output downwards. Ensure the final hopper is placed directly on top of the crucible. Check Item Transfer Node connections and filters. Is the crucible full of lava? If the output isn’t piped away, lava builds up and stops new cobblestone from entering. Pipe the lava out!
How do I make the crucible melt faster? Upgrade your heat source. Netherrack fire is slow. Lava underneath is better. The Heater block (from Ex Nihilo Creatio), powered by RF, is the fastest option. Increase the number of crucibles fed by one generator.
Can I use stone or gravel instead of cobblestone? Yes! Crucibles can melt cobblestone, stone, and gravel into lava. Stone and gravel melt at the same rate as cobblestone. Use whatever your generator produces or what you have excess of.

Is there a better way to generate cobblestone? The basic water+lava generator works well. Later, you can use machines like the Automated User clicking on a cobblestone formation or even more advanced block generators from other mods. The connection principle to the crucible remains similar – automate item transfer.
