Smooth stone creates a clean surface for floors, workshops, and building details. It is different from ordinary stone and from polished versions of other blocks. Check the name of the furnace output before preparing a batch, especially if you are collecting materials for a specific design.
From cobblestone to smooth stone
Smelt cobblestone in a furnace to produce stone, then smelt that stone again to obtain smooth stone. You need fuel for both stages. Use a regular furnace and check the recipe supported by your game version. If you already have ordinary stone, begin with the second stage. Keeping each material separate helps you track which part of the process you have completed.
Organize your furnace work
- Measure the area you want to cover and prepare a small sample first.
- Keep cobblestone, stone, and smooth stone in separate chest slots.
- Provide enough fuel to finish the batch and check each output before moving it.
- Try the blocks beside wood or bricks before replacing the whole floor.
Smooth stone also appears in other recipes, including the blast furnace. Set aside a few blocks for useful equipment before spending the entire batch on decoration. A small test section of flooring will show whether the color and texture suit the room before renovating.
