What is how to make smooth stone in minecraft?

To make smooth stone in Minecraft, you will need the following:

1. Cobblestone: You'll need to first gather cobblestone. This is obtained by mining any stone block with a pickaxe.
2. Furnace: Place the cobblestone in a furnace as input and use any fuel source (like coal, wood, or charcoal). This process will smelt the cobblestone into stone.
3. Smelting Stone to Smooth Stone: Take the stone that you just created and place it back into the furnace. Smelt it again using any fuel source. This will result in smooth stone.
