Stone Bricks or brick block is a quite durable material that is crafted of 4 cobblestone blocks. It is a very good building material if the player wants to build walls or floor for a house. It is not present in recipes, so that's all it can be used for at the moment. Every four cobblestone blocks can be converted into four stone bricks, so you don't lose any cobblestone in the process.
