How to Make Smooth Stone in Minecraft
To make Smooth Stone in Minecraft, smelt Cobblestone into Stone, then smelt that Stone a second time. This guide shows the exact furnace recipe, the Blast Furnace method, fuel math and a step-by-step walkthrough for Java and Bedrock.
The short answer
Smelt Cobblestone into Stone, then smelt that Stone again. Smooth Stone never drops directly from mining, and there is no crafting recipe for it — it always requires two passes through a furnace.
- Step 1: Cobblestone → Furnace → Stone
- Step 2: Stone → Furnace → Smooth Stone
A Blast Furnace performs Step 2 twice as fast, but it cannot accept Cobblestone, so most players use a standard Furnace for Step 1 and keep a Blast Furnace next to it for polishing bulk Stone.
What you need before you start
| Item | How to get it | Why you need it |
|---|---|---|
| Furnace | Craft 8 Cobblestone in a ring on a Crafting Table | Required to smelt Cobblestone into Stone |
| Blast Furnace (optional) | Craft with 5 Iron Ingots, 1 Furnace, 3 Smooth Stone | Doubles polishing speed for Step 2 |
| Fuel | Coal, Charcoal, Wood, or a Bucket of Lava | One unit smelts eight items |
| Cobblestone | Any pickaxe, or a Cobblestone Generator | Starting material |
| Pickaxe | Wooden tier or better | Silk Touch required to mine Stone directly |
Tip: If you mine Stone with a Silk Touch pickaxe you can skip Step 1 entirely, because the block drops as Stone instead of Cobblestone.
How to make Smooth Stone step by step
Step 1 — Get Cobblestone
Mine any stone-type block with a pickaxe. Any tier works, but nothing drops if you break stone by hand. For an infinite supply, build a cobblestone generator: place a lava source above a channel and let it flow onto flowing water, which hardens into Cobblestone you can mine endlessly.
Step 2 — Smelt Cobblestone into Stone
- Right-click your Furnace to open its interface.
- Put Cobblestone in the top slot (input).
- Put your fuel in the bottom slot.
- Wait for the arrow to fill, then take Stone from the right slot.
Each fuel unit processes eight blocks, so one Coal gives you eight Stone.
Step 3 — Smelt the Stone a second time
- Keep the Furnace open and move the fresh Stone into the input slot.
- Let it smelt again.
- Collect Smooth Stone from the output slot.
That second pass is the whole secret — skipping it is the most common reason players cannot find the recipe.
Step 4 — Scale up with multiple furnaces
For large modern builds you will burn through thousands of blocks. Place a row of Furnaces fed by hoppers, or use a Blast Furnace array for Step 2. A single Blast Furnace polishes roughly twice as many blocks per minute as a Furnace, which matters when you need a full shulker box of Smooth Stone Slabs.
Blast Furnace vs Furnace
| Feature | Furnace | Blast Furnace |
|---|---|---|
| Cobblestone → Stone | Yes | No, it rejects Cobblestone |
| Stone → Smooth Stone | Yes | Yes, at double speed |
| Crafting cost | 8 Cobblestone | 3 Smooth Stone, 5 Iron Ingots, 1 Furnace |
| Best use | General smelting | Bulk stone polishing after Step 1 |
If you want a fully automatic line, run Furnaces for Step 1, pipe the Stone into Blast Furnaces, and pipe the Smooth Stone output into a Stonecutter area for slabs and stairs.
What Smooth Stone is used for
- Smooth Stone Slabs — 3 Smooth Stone makes 6 slabs, the cleanest-looking grey surface in the game.
- Smooth Stone Stairs — 6 Smooth Stone makes 4 stairs, ideal for bunker and base interiors.
- Blast Furnace crafting — every Blast Furnace costs 3 Smooth Stone, so you need at least three blocks to build your first one.
- Modern build palettes — pairs cleanly with Deepslate, Tuff and Calcite for contrast.
Troubleshooting
Nothing happens when I put Cobblestone in the Blast Furnace. Working as intended. Blast Furnaces only accept ore blocks, raw metals and metal items. Use a regular Furnace for Step 1.
I keep getting Stone instead of Smooth Stone. You are only doing one smelt. Take the Stone output and smelt it again.
The recipe seems slow. Upgrade your fuel. Coal and Charcoal smelt 8 items each, while a single Bucket of Lava smelts 100 items, and Dried Kelp Blocks are the fastest renewable early option.

Frequently Asked Questions
How do you make Smooth Stone in Minecraft?
Put Cobblestone in a Furnace to get Stone, then put that Stone back into a Furnace. The second smelt turns Stone into Smooth Stone. Two smelting steps are always required, because there is no direct Cobblestone to Smooth Stone recipe.
Can a Blast Furnace make Smooth Stone?
Yes. A Blast Furnace smelts Stone into Smooth Stone twice as fast as a regular Furnace, but it only accepts ore, raw metals, iron and gold tools and armour. That means you must use a normal Furnace or blast-proof setup first if starting from Cobblestone.
Why is my Smooth Stone not crafting into slabs or stairs?
Smooth Stone Slabs and Smooth Stone Stairs come from Smooth Stone blocks and require a Stonecutter or Crafting Table. If nothing happens, check that you are holding Smooth Stone and not ordinary Stone, which looks similar but has speckled edges.
Is Smooth Stone the same as Stone Bricks?
No. Smooth Stone is the plain polished block used for modern builds, while Stone Bricks are a separate four-block crafting recipe and are never made in a Furnace.
