You've spent three hours mining. Your inventory is a mess of raw iron, gold ore, and stacks of cobblestone that you don't really know what to do with yet. You head back to your dirt hut or your mountain fortress, and you realize the single furnace sitting in the corner just isn't going to cut it. It’s slow. It’s tedious. Watching that little flame icon flicker while you wait for 64 iron ingots to cook is basically the Minecraft equivalent of watching paint dry. Honestly, if you’re still clicking into a single furnace every few minutes to swap out stacks, you're playing the game on hard mode for no reason.
Learning how do I make a smelter in Minecraft isn't just about knowing a crafting recipe; it’s about understanding how to automate the boring stuff so you can get back to exploring the Deep Dark or building that unnecessarily large statue of a chicken.
The Basic Furnace: Where Everyone Starts
Before we get into the complex stuff, let’s talk about the humble furnace. You need eight pieces of Cobblestone, Blackstone, or Cobbled Deepslate. You arrange them in a circle in your crafting table, leaving the middle square empty. Simple. This is your workhorse for the first few days of any survival world.
But here is the thing: the standard furnace is a generalist. It cooks food and it smells ore. Because it does both, it’s not particularly fast at either. If you have a stack of 64 Raw Iron, a standard furnace will take exactly 800 seconds to finish the job. That’s over 13 minutes of your life you aren't getting back.
Most players stop here. They just craft ten furnaces, line them up against a wall, and manually fill them with coal and ore. It works, sure, but it's messy. You're constantly running back and forth, checking which furnace is empty and which one is finished. There is a much better way to handle your resources once you have a little bit of iron to spare.
Specialization is the Name of the Game
If you want to be efficient, you have to stop using the basic furnace for everything. Minecraft introduced specialized smelting blocks a while ago, and they are game-changers.

The Blast Furnace
If your question is specifically "how do I make a smelter in Minecraft" because you have too much iron and gold, the Blast Furnace is your best friend. It smelts ores, raw metals, and even iron/gold tools or armor twice as fast as a regular furnace.
To craft one, you’ll need:
- One regular Furnace
- Five Iron Ingots
- Three pieces of Smooth Stone (not regular stone, but stone that has been smelted twice)
The tradeoff? It only cooks "ore" items. You can't put a raw porkchop in a Blast Furnace. It’ll just sit there. But for clearing out a chest full of raw copper? It’s indispensable.
The Smoker
On the flip side, if you're starving and need food fast, you want a Smoker. It’s the culinary brother of the Blast Furnace. It cooks food at double the speed of a regular furnace. You make it by surrounding a furnace with four logs or stripped logs. It’s cheap, effective, and keeps you from dying of hunger while you’re busy building.
The "Auto-Smelter" and Why You Need One
Knowing the recipe for a furnace is one thing. Building a "smelter"—which most players define as an automated system—is where the real Minecraft starts. To do this, you need Hoppers.
Hoppers are expensive for early-game players (five iron ingots and a chest each), but they are the "veins" of any automated system. A basic auto-smelter consists of three parts:
- The Input: A chest on top of a hopper that leads into the top of the furnace. This is where you put your raw ore.
- The Fuel: A chest on the side of a hopper that leads into the side of the furnace. This is where you put your coal, charcoal, or lava buckets.
- The Output: A hopper underneath the furnace that leads into a final collection chest.
Basically, you dump your loot in the top, walk away, and come back later to find finished ingots in the bottom chest. No clicking. No waiting. It just works.
The Fuel Problem
Kinda funny how many people forget the fuel. If you’re using coal, you’re going to run out eventually. If you’re serious about your Minecraft smelter, you should start looking into Lava Buckets. A single bucket of lava lasts for 1,000 seconds and can smelt 100 items.
If you find a dripstone cave, you can actually set up a "Pointed Dripstone" over a cauldron with lava above it. This creates an infinite lava source. Now, your smelter has infinite fuel. That’s the dream.
Advanced Super-Smelters: The Industrial Revolution
So, you’ve got a basic auto-smelter, but you’re still impatient. You want something that can smelt a double chest of items in minutes. This is where "Super-Smelters" come in.
These builds use minecarts with chests to distribute items across 8, 16, or even 64 furnaces at once. Instead of one furnace doing all the work, the minecart zips across the top, dropping one ore into each furnace.
It sounds intimidating, but it's really just a long row of furnaces with hoppers on top. You run powered rails over the hoppers. When the minecart passes over, the hoppers "suck" the items out of the cart and push them into the furnaces. It’s loud, it’s flashy, and it makes you feel like a redstone genius.
Common Mistakes to Avoid
- Using the wrong stone: I've seen so many people try to craft a Blast Furnace with Cobblestone. It has to be Smooth Stone. Smelt Cobblestone to get Stone, then smelt that Stone again to get Smooth Stone.
- Hopper Direction: This is the big one. If your hopper isn't "pointing" into the furnace, it won't work. Look at the little nozzle at the bottom of the hopper. It needs to be angled toward the block you want to fill.
- Experience Points: When you use a hopper to pull items out of a furnace, you don't get the XP automatically. It stays "stored" in the furnace. To get that sweet, sweet level-up juice, you have to break the furnace or occasionally pull an item out by hand.
Beyond the Basics: Soul Sand and Water Elevators
If you’re building your smelter in a basement, you might want your finished items to be delivered to your main floor. This is where soul sand water elevators come in. You can have your output hopper drop items into a "dropper" block, which shoots them into a bubble column. The items float up to the top and land in a chest right in your kitchen.
Is it overkill? Maybe. But Minecraft is a game about overkill.
Actionable Steps for Your World
If you just started a new world, don't try to build a 64-furnace array immediately. Start small and scale up as your iron reserves grow.
- Phase 1: Craft 4 standard furnaces and place them in a row. Manually fuel them with logs if you have to.
- Phase 2: Replace two of those furnaces with Blast Furnaces. Use the iron you just smelted to make your first 6 Hoppers.
- Phase 3: Set up a "vertical" auto-smelter. Chest -> Hopper -> Blast Furnace -> Hopper -> Chest.
- Phase 4: Expand horizontally. Link multiple furnaces together using a rail system and a chest minecart to distribute your ores evenly.
Once you have a functional smelter, the game changes. You stop worrying about "having enough iron" and start worrying about what you're going to build with all that iron. Go find a dripstone cave for that infinite lava, and you'll never have to mine coal again. Just keep a stack of empty buckets nearby, and you're golden. Literally, if you're smelting gold.
