To obtain smooth stone in Minecraft, you'll need to follow these steps:
1. **Mine Cobblestone**: First, you need to mine cobblestone. Cobblestone is a common block found underground, especially in caves, mineshafts, and ravines. You can also create cobblestone by mining stone with a pickaxe without the Silk Touch enchantment.
2. **Smelt Cobblestone**: Once you have cobblestone, place it in a furnace along with a fuel source such as coal, charcoal, or wood. Each piece of cobblestone will smelt into one block of regular stone. You can use any furnace to smelt cobblestone.
3. **Craft Smooth Stone**: To create smooth stone, place the stone blocks you obtained from smelting cobblestone into a crafting table. Arrange the stone blocks in a 2x2 square grid, leaving the center empty. This will create four smooth stone blocks.
4. **Smelt Smooth Stone (Optional)**: If you want to obtain more smooth stone, you can smelt the smooth stone blocks you crafted in a furnace. Each smooth stone block smelts into one block of smooth stone.
That's it! You now have smooth stone, which can be used for building, decoration, or crafting various items in Minecraft.
