How to Make a Furnace in Minecraft: Recipe, Fuel, and Uses
To make a furnace in Minecraft you place eight cobblestone around the outer edge of a crafting table, leaving the center empty. Here is how to make a furnace in Minecraft, step by step, from mining the stone to smelting your first iron.
A furnace turns raw materials into useful items. It cooks food, smelts ore into ingots, and bakes sand into glass, so it is one of the first blocks every new world needs.
Mine the Cobblestone You Need
The only ingredient is cobblestone, which drops when you break stone with a pickaxe. Wood, gold, and diamond pickaxes all work, but a stone pickaxe is the cheapest reliable choice.
- Craft a pickaxe from three planks and two sticks in the top row of the grid.
- Dig down or into a hillside until you reach grey stone below the dirt layer.
- Break at least eight stone blocks, which drop as cobblestone you can pick up.
Tip: Mine ten or twelve blocks instead of eight. The spare cobblestone lets you craft a second furnace later without another trip.
The Exact Crafting Table Layout
A furnace needs the full 3×3 grid, so you must use a crafting table rather than the small inventory grid. Open the table and fill every slot except the middle.
- Top row: place one cobblestone in each of the three slots.
- Middle row: place cobblestone on the left and right, and leave the center empty.
- Bottom row: place one cobblestone in each of the three slots.
The furnace appears in the result slot as soon as the ring is complete. Drag it into your hotbar so you can place it quickly.
Place the Furnace and Add Fuel
Put the furnace on any solid block by pressing use (right-click on PC). Then open it to see three slots: a top input, a bottom fuel slot, and an output on the right.
- Add fuel to the bottom slot. Coal, charcoal, wood, or planks all burn.
- Add the item to smelt in the top slot, such as raw iron or raw food.
- Wait as the arrow fills, then collect the finished item from the output.
Each piece of coal smelts eight items, which makes it the most convenient early fuel. Charcoal, made by smelting logs, works exactly the same if you have not found coal yet.
Note: A lava bucket is the longest-lasting fuel in the game, smelting up to one hundred items, but you lose the bucket unless you use a hopper setup.
What a Furnace Can Smelt
The furnace handles a wide range of jobs, and knowing the outputs helps you plan mining trips. This table covers the most common inputs new players use.
| Input | Output | Common use |
|---|---|---|
| Raw iron | Iron ingot | Tools, armor, buckets |
| Raw gold | Gold ingot | Powered rails, golden apples |
| Sand | Glass | Windows, bottles |
| Raw chicken | Cooked chicken | Restoring hunger |
| Cobblestone | Stone | Cleaner building blocks |
Smelting always gives better results than eating raw or using unprocessed blocks. Cooked food restores far more hunger than raw food, and ingots are the only way to reach iron and gold gear.
Upgrade to a Blast Furnace
Once you have iron, you can build a blast furnace that smelts ore and metal tools twice as fast as a normal furnace. It cannot cook food, so keep your original furnace too.
- Gather five iron ingots, three smooth stone, and one regular furnace.
- Smelt cobblestone into stone, then stone into smooth stone to get the three smooth stone blocks.
- Arrange them with iron across the top, the furnace in the center, smooth stone on the sides of it, and smooth stone across the bottom.
The blast furnace is the fastest choice for large ore hauls. For everything else, including cooking meat and baking glass, the standard furnace remains the reliable tool once you know how to make a furnace in Minecraft.
Handy Furnace Tips for Early Survival
A few small habits make your furnace far more useful during the first days of a world.
- Keep it fueled and running while you do other tasks, since smelting continues even when the menu is closed.
- Batch your ore so a full stack smelts in one go rather than one piece at a time.
- Place two or three furnaces side by side to process large hauls in parallel.
- Store charcoal as backup fuel so you never stall a smelt waiting to find coal.
With one furnace fueled and a small coal supply, you can turn a night of mining into a full set of iron gear by morning. That single block is the bridge between raw resources and everything you build next.
Frequently Asked Questions
How much cobblestone does a furnace need? Exactly eight cobblestone, placed in a ring around the crafting grid with the center slot left empty.
Can I use regular stone instead of cobblestone? No. The recipe requires cobblestone specifically. If you smelt cobblestone into smooth stone, it will not work for the furnace.
What is the best furnace fuel? Coal and charcoal are the easiest, smelting eight items each. Lava buckets last longest, and a blast of dried kelp blocks is great for automatic farms.
Why is my furnace not smelting? Check that you have both fuel in the bottom slot and a smeltable item in the top slot. Blocks like dirt and wood planks cannot be smelted.
What is the difference between a furnace and a blast furnace? A blast furnace smelts ore and metal tools twice as fast but cannot cook food. Keep a normal furnace for meals and glass.
