Make charcoal by smelting any wooden log or stripped-log variant in a furnace. Place the log in the top input slot, add planks, sticks, a wooden tool, or another valid furnace fuel in the bottom slot, then wait for the smelt to finish. The Minecraft Wiki beginner tutorial gives a 10-second smelting time per item. The resulting charcoal is renewable because trees can supply more logs whenever you need them.
What you need
The recipe has no crafting-grid pattern. You need three things: a log, a furnace, and fuel for the furnace.

- One wooden log: Any log works. The cited Minecraft Wiki reference also accepts stripped-log variants.
- A furnace: Craft and place one before starting the smelt.
- Starter fuel: Planks, sticks, wooden tools, or another item accepted by the furnace can power the first cycle. You do not need coal to begin.
Logs from different tree types serve the same charcoal purpose. Keep the log intact or strip it; both forms can be smelted according to the current Minecraft Wiki reference.
Step-by-step: smelt a log into charcoal
- Collect a log. Break a tree trunk and pick up at least one log. If you have already used an axe to strip the log, that stripped version is also accepted by the recipe reference.
- Craft a furnace. Use the standard furnace recipe, then place the furnace on a solid, accessible block.
- Open the furnace. The interface has a top input slot, a bottom fuel slot, and an output slot on the right.
- Insert the log. Put the regular or stripped log into the top input slot. Do not put it in the fuel slot; the furnace treats the two slots differently.
- Add fuel. Place planks, sticks, a wooden tool, or another valid furnace fuel in the bottom slot. For a first cycle, use only enough fuel to process the number of logs you inserted.
- Wait for the arrow to fill. The beginner tutorial cited by Minecraft Wiki states that each item takes 10 seconds to smelt. The furnace burns fuel while the progress arrow advances.
- Collect the charcoal. Move the finished charcoal from the output slot into your inventory. Leave the furnace running if additional logs remain in the input slot and fuel remains below.
Minecraft’s official guidance summarizes the process as chopping down a tree, putting the logs in a furnace, and waiting a few moments. The separate fuel slot is the detail that commonly stops a first attempt: a log by itself will not smelt.

How the furnace cycle works
Input and fuel are separate
The top slot determines what the furnace processes. The bottom slot determines what supplies heat. A log in the top slot with an empty fuel slot simply sits there. Conversely, fuel in the bottom slot cannot turn into charcoal; it only powers the furnace.
Smelting time
The Minecraft Wiki beginner tutorial lists 10 seconds for each smelted item. If you load several logs, the furnace processes them one at a time, so a larger batch takes longer unless you use multiple furnaces. The progress bar shows whether the current item is still being processed.

Charcoal appears in the output slot after a cycle completes. You can take it out while the furnace continues processing the next input. If the output slot is full, production pauses until you make room.
What to use as your first fuel
When coal is unavailable, start with a small amount of wood fuel. Planks and sticks are easy to make immediately after collecting logs. Wooden tools that have nearly reached their durability limit can also be used if the furnace accepts them as fuel. Other valid furnace fuels work as well, but early-game wood is usually the most accessible option.
Use a small starter batch
Do not convert every log in your inventory at once if you have only a few planks or sticks. Put one or two logs in the furnace and match the fuel to that batch. This gives you charcoal quickly without leaving a large amount of wood waiting for heat.
Turn the first charcoal into more fuel
Once the first piece is ready, use charcoal to power additional log batches. A renewable loop is then available: harvest trees, smelt logs, and use the charcoal from one batch to process the next. You still need to provide logs, but no mined coal is required.

One log produces one charcoal when smelted. The cited Minecraft Wiki charcoal entry reports 80 seconds of burn time for one charcoal and says it can smelt up to eight items. That capacity is useful when planning a batch: eight smelts use the published maximum, while a smaller batch leaves some potential burn time unused.
Match fuel to the workload
The Minecraft Wiki smelting tutorial recommends matching fuel amounts to the batch size when possible. If you need to process only a few logs, do not automatically fill the fuel slot with a large stack. If you are preparing a long run, load enough logs and fuel to keep the furnace working rather than repeatedly reopening it.
| Situation | Practical approach | Reason |
|---|---|---|
| First furnace cycle | Use planks or sticks with one or two logs | Gets the first charcoal without consuming your entire wood supply |
| Several logs ready | Use charcoal or another fuel for a matched batch | Reduces idle furnace time and unused burn time |
| Large quantity | Split work among multiple furnaces if available | Each furnace processes its own item every 10 seconds |
| Fuel is scarce | Process only the number of logs your fuel can support | Prevents an unfinished batch from sitting in the input slot |
What charcoal is used for
Charcoal is both a furnace fuel and a crafting ingredient for early-game fire and lighting items. The official Minecraft article lists these uses:
- Fuel: Burn charcoal in a furnace and use its published 80-second burn time to process up to eight items.
- Torches: Combine charcoal with a stick to make a basic torch for lighting caves, shelters, and paths.
- Soul torches: Use charcoal in the torch recipe when making the soul variant with the required soul-related materials.
- Campfires: Charcoal is among the materials named by the official guidance for campfire crafting.
- Fire charges: The official article also names charcoal as a fire-charge ingredient.
Recipes can require additional ingredients, and the exact recipe display depends on your edition and game version. If a recipe does not appear, check the in-game recipe book for the materials available in your world.

Charcoal, coal, and ordinary wood fuels compared
Charcoal is most valuable when you have trees but have not yet found a dependable coal supply. Coal is obtained by mining, while charcoal comes from renewable tree logs. Both choices occupy furnace fuel slots, but the setup and availability differ.
| Option | How you obtain it | Burn information established by the cited material | Setup effort | Best use case |
|---|---|---|---|---|
| Charcoal | Smelt a log or stripped log in a furnace | 80 seconds; up to eight smelted items per charcoal | Furnace, a log, and starter fuel | Renewable fuel before or instead of mining coal |
| Coal | Mine coal ore | Not stated in the supplied material | Mining and furnace access | Fuel when a coal supply is already available |
| Planks or sticks | Craft from harvested wood | Item-specific values are not stated in the supplied material | Immediate access after chopping trees | Starting the first charcoal cycle |
| Wooden tools | Craft wooden tools, then use them as fuel | Item-specific values are not stated in the supplied material | Requires tool crafting | Using worn or surplus wooden tools |
Do not assume charcoal is the most efficient wood-based fuel in every edition. The cited beginner tutorial specifically notes that Bedrock Edition slabs can be more efficient than converting wood into charcoal. Edition-specific fuel comparisons should therefore be checked in the version you play.

Java and Bedrock Edition considerations
The core recipe is the same furnace process in both major editions: a log or stripped log goes into the input slot, fuel goes below it, and the furnace produces charcoal. The difference matters when you compare fuel efficiency rather than when you make the item.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsRecipe consistency
You can follow the seven-step procedure above in Java or Bedrock Edition. The furnace interface may look slightly different depending on your platform, but the input, fuel, and output roles remain distinct.
Fuel-efficiency caveat for Bedrock
The Minecraft Wiki beginner tutorial points out that Bedrock slabs can outperform the wood-to-charcoal route in fuel efficiency. That does not prevent charcoal from being useful: charcoal remains renewable, portable, and suitable for the listed furnace and crafting uses. It means that a player optimizing every plank should compare slabs with charcoal in the specific Bedrock version being played instead of assuming one universal winner.

The log is not smelting
- Check that the log is in the top input slot, not the bottom slot.
- Check that at least one valid fuel item is in the bottom slot.
- Make sure the furnace is placed and opened rather than using a crafting table.
- Remove any finished item from the output slot if it is full.
The furnace stops partway through
The fuel supply has probably been exhausted. Add another valid fuel item to the bottom slot. If the input stack is large, compare its size with the burn capacity of the fuel you supplied so the next batch does not remain unfinished.
The output is missing
Wait for the progress arrow to complete. A furnace does not create charcoal instantly; the cited tutorial gives 10 seconds per item. Also inspect the output slot before adding more input, because a full output slot prevents the furnace from continuing.
A stripped log is rejected
The current Minecraft Wiki recipe reference accepts stripped-log variants. If your game does not, verify that you are using a log item rather than another wood block and check the recipe book for your exact edition and version.
You ran out of starter fuel
Harvest more wood and craft some planks or sticks. You can also use another item listed as a valid furnace fuel, including a suitable wooden tool. One successful cycle supplies charcoal for later batches.
A reliable early-game charcoal workflow
- Harvest several logs while leaving enough wood for tools, shelter, and planks.
- Craft and place a furnace near your work area.
- Reserve a small number of planks or sticks as starter fuel.
- Smelt a controlled first batch of logs.
- Move the charcoal to your inventory as soon as it appears.
- Use the charcoal to process additional logs in batches sized to the available burn time.
- Keep a reserve of charcoal for torches, cooking, and emergency furnace work instead of spending every piece on one long run.
This workflow avoids the usual progression trap: waiting for coal before you can make light or cook. Trees provide both the raw material and, after the first cycle, the renewable fuel source.
When charcoal is the right choice
Choose charcoal when you have a steady supply of logs, need fuel before mining, or want a renewable source near a base. It is particularly convenient for a new world because the only required infrastructure is a furnace and a little starter fuel.
Choose another wood fuel when you are optimizing a Bedrock build and have confirmed that slabs are more efficient for your workload, or when you need to start a furnace before any charcoal exists. Choose mined coal when exploration has already produced a reliable supply and you prefer to reserve logs for building or other crafting.
